Abstract

Systems and methods are described that enable collaboration in interactive sessions. A first connection is established between a terminal client and a relay service and the terminal client engages in an interactive session with a terminal service. A second connection is established between a shadow client and the relay service and data and commands are relayed between the terminal client and the shadow client through the relay service, The first and second connections and the interactive session may be encrypted. The interactive session is encrypted using different encryption keys than the keys used by the first and second connections. The data and commands include information associated with the interactive session and the information may be used to synchronize displays between the terminal client and the shadow client.

Claims

1. A method of collaborating in an interactive session, comprising:

establishing a first connection between a terminal client and a relay service, wherein the terminal client is configured to engage in an interactive session with a terminal service;

creating a second connection between a shadow client and the relay service; and

relaying data and commands between the terminal client and the shadow client through the relay service, wherein certain of the data and commands provided by the shadow client are transmitted to the terminal service in the interactive session.

2. The method of claim 1, wherein at least one of the first connection and the second connection is encrypted.

3. The method of claim 1, wherein the interactive session is encrypted.

4. The method of claim 3, wherein the interactive session is encrypted using first encryption keys and wherein the first and second connections are encrypted using different encryption keys.

5. The method of claim 4, wherein the terminal client decrypts the data and commands relayed from the shadow client and re-encrypts certain of the data and commands using the first encryption keys.

6. The method of claim 4, and further comprising providing an encrypted channel between the terminal client and the shadow client, wherein a portion of the communications in the encrypted channel is relayed without decryption at the relay service.

7. The method of claim 6, wherein the portion of the communications includes payload data.

8. The method of claim 1, wherein the data and commands include information associated with the interactive session.

9. The method of claim 8, wherein the information is used to synchronize displays between the terminal client and the shadow client.

10. The method of claim 8, wherein the information comprises communications between users of the terminal client and the shadow client.

11. The method of claim 10, wherein the communications between users includes voice communications.

12. The method of claim 10, wherein the communications between users includes chat.

13. The method of claim 1, and further comprising selectively filtering portions of the data and commands originating at the shadow client.

14. The method of claim 13, wherein filtering includes blocking user input.

15. The method of claim 1, and further comprising selectively filtering portions of the data and commands transmitted by the terminal client.

16. The method of claim 15, wherein filtering includes blocking user input.

17. The method of claim 1, and further comprising creating one or more additional connections between one or more corresponding additional shadow clients and the relay service.

18. The method of claim 1, and further comprising establishing a peer-to-peer communications channel between the terminal client and the shadow client, wherein the peer-to-peer communications channel is provided separately from the first and second connections.

19. The method of claim 1 and further comprising logging the data and the commands observed at least one of the terminal client, the shadow client and the relay service.

20. The method of claim 19, wherein logging includes maintaining a history of a terminal service protocol and user interactions.

21. A system providing for collaboration in an interactive session, comprising a relay configured to support a plurality of communications channels between terminal clients including a collaborative communications channel between a first terminal client and at least one shadow client, wherein the first terminal client establishes the interactive session with a terminal service and wherein the relay synchronizes displays between the first terminal client and the at least one shadow client, the at least one shadow client contributing input to the interactive session.

22. The system of claim 21, wherein the interactive session is encrypted using first encryption keys and wherein the first and second connections are encrypted using other encryption keys different from the first encryption keys.
