MPX is a way to have multiple pointers in a X-Windows system. The usual X-Windows systems supports multiple input devices, but just one pointer.

• What about FocusShare in Windows? Does it already the distribution we need?

> Seems to be orientated towards video etc.

• And can we combine that with CPNmouse which supports multiple mice in Windows (see also the sources here)?

(1) Seperate the existing into input part to event stream tranformation (2) Care for local IPC connection. (3) Write an event stream server prototype: Needs connection handling + protocol implementation. (3) Write an event stream client prototype: Needs connection handling + protocol implementation. (4) What protocol to use? RFB? rdesktop?
