Claims

1. In a distributed computer network where displayed information is shared between at least two computers, a method of displaying shared images comprising the steps of:

identifying image data of one computer that is to be shared with at least one other computer during a presentation;

transmitting the identified image data to said at least one other computer for display; and

providing feedback at least one of said one and other computers concerning the position of the at least one other computer within the presentation.

2. The method of claim 11 wherein the feedback is visual and is provided at both of said one and other computers.

3. The method of claim 12 wherein the feedback identifies when the at least one other computer falls behind in the presentation.

4. The method of claim 13 further comprising:

forcing the at least one other computer is selectively forced to catch up in the presentation.

5. The method of claim 14 wherein the at least one other computer is forced to catch up in the presentation if the at least one other computer falls behind by a pre-determined period of time in the presentation.

6. In a distributed computer network where displayed information is shared between at least two computers, a method of displaying shared images comprising the steps of:

identifying image data of one computer that is to be shared with at least one other computer during a presentation;

transmitting the identified image data to said at least one other computer for display;

detecting other computers that fall behind in the presentation; and

forcing other computers that fell behind in the presentation to catch up.
