conveying the loaner license to a borrowing client.

2. [claim_M_BB]The method of claim 1 wherein receiving a request to share a digital license comprises receiving at least one of an electronic message from the borrowing client and receiving an electronic message from a licensing authority.

3. The method of claim 2 further comprising:

making a local user aware of the request; and

receiving an allow-loan indication from a local user.

4. The method of claim 1 wherein receiving a request to share a digital license comprises receiving at least one of an encryption key and a borrower-specific identifier.

5. The method of claim 1 wherein receiving a request to share a digital license comprises receiving a request to share a license from a local user.

6. [claim_M_BA]The method of claim 1 wherein preparing a loaner license comprises:

determining when the current license can be shared;

creating a loaner license when the current license can be shared.

7. The method of claim 6 wherein determining when the current license can be shared comprises:

determining a share quantity limit for the current license;

marking the current license as sharable when the share quantity limit has not been exceeded; and

updating the share quantity limit for the current license to reflect the creation of a loaner license.

8. The method of claim 6 wherein determining when the current license can be shared comprises:

determining a share depth limit for the current license;

marking the current license as sharable when the share depth limit has not been exceeded; and

updating the share depth limit for the current license to reflect the creation of a loaner license.

9. The method of claim 1 wherein preparing a loaner license comprises:

creating a loan-limit indicator that includes at least one of a share-quantity limit indicator, a share-quantity limit for a time period indicator, a share depth indicator, an expiration epoch indicator, a use-limit indicator and a borrower-specific identifier; and

creating a loaner license that includes the created loan-limit indicator.

10. The method of claim 1 wherein conveying the loaner license comprises:

encrypting the loaner license according to an encryption key received in association with a request to borrow a license; and

electronically conveying the encrypted loaner license to a borrower client.

11. The method of claim 1 wherein conveying the loaner license comprises conveying the loaner license to a license authority.

12. The method of claim 1 further comprising providing a content file which is associated with the current license to the borrowing client.

13. The method of claim 1 further comprising marking the current license as “

on-loan”

.

14. [claim_A_A]An apparatus for sharing a digital access license comprising:

processor capable of executing an instruction sequence;

communications interface capable of sending and receiving information;

memory capable of storing one or more instruction sequences and further capable of storing information; and

one or more instruction sequences stored in the memory including;

protocol stack that, when executed by the processor, minimally causes the processor to establish a communications connection using the communications interface; and

license manager that, when executed by the processor, minimally causes the processor to;

receive a request to share a digital access license stored in the memory;

identify a current license stored in the memory according to the request to share a digital access license;

execute the protocol stack in order to establish a communications connection;

prepare a loaner-license according to the identified current license; and

convey the loaner-license to the established connection.

15. [claim_A_AA]The apparatus of claim 14 further comprising an electronic mail module stored in the memory that, when executed by the processor, minimally causes the processor to receive an electronic mail message wherein the license manager causes the processor to receive a request to share a digital access license by minimally causing the processor to:

execute the electronic mail module in order to receive an electronic mail message; and

extract a request to share a digital access license from a received electronic mail message when the received electronic mail message is received from at least one of a borrowing client and a licensing authority.

16. The apparatus of claim 15 further comprising a user input unit and a user output unit wherein the license manager further minimally causes the processor to:

direct a message to the user output device according to the received request to share a digital access license; and

receive from the user input device an allowance indicator.

17. The apparatus of claim 14 wherein the license manager causes the processor to receive a request to share a digital access license by minimally causing the processor to receive by means of the communications interface at least one of an encryption key and a borrower-specific identifier.

18. The apparatus of claim 14 further comprising a user input device wherein the license manager causes the processor to receive a request to share a digital access license by minimally causing the processor to receive a request to share a digital access license by means of the user input device.

19. [claim_A_AB]The apparatus of claim 14 wherein the license manager causes the processor to prepare a loaner-license by minimally causing the processor to:

determine when a current identified license stored in the memory is shareable; and

create a loaner-license according to the current identified license stored in the memory when the current identified license is shareable.

20. The apparatus of claim 14 wherein the license module causes the processor to determine when a current license is sharable by minimally causing the processor to:

retrieve a share-quantity limit included in the current identified license to be shared;

note that the current identified license as shareable when the retrieved share-quantity indicator indicates that the current identified license is shareable; and

update the share-quantity limit in the current identified license in order to reflect the creation of a loaner-license.

21. The apparatus of claim 14 wherein the license module causes the processor to determine when a current license is sharable by minimally causing the processor to:

retrieve a share-depth limit included in the current identified license to be shared; and

note that the current identified license as shareable when the retrieved share-depth indicator indicates that the current identified license is shareable.

22. The apparatus of claim 14 wherein the license module causes the processor to prepare a loaner-license by minimally causing the processor to:

create a loan-limit indicator that comprises at least one of a share-quantity limit indicator, a share-quantity for a time period indicator, a share depth indicator, an expiration epoch indicator, a use-limit indicator and a borrower-specific identifier; and

create a loaner-license that includes the loan-limit indicator.

23. The apparatus of claim 14 further comprising an encryption module stored in the memory that, when executed by the processor, minimally causes the processor to encrypt a loaner-license stored in the memory according to an encryption key that is also stored in the memory wherein the license manager causes the processor to convey a loaner-license to a borrowing client by minimally causing the processor to:
