 [[http://wearables.unisa.edu.au/mpx/?q=documentation|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 [[http://ship.nime.ac.jp/~osawa/focusShare/031211/readme.html|FocusShare]] in Windows? Does it already the distribution we need? And can we combine that with [[http://cpnmouse.sourceforge.net/|CPNmouse]] which supports multiple mice in Windows (see also the sources [[http://link.mywwwserver.com/~jstookey/arcade/rawmouse|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?
