One of the reasons I sent the mouse click positions as time stamped
datagrams was to develop a general set of plain "c" code to hack  around
interfaces for hacks like this. It is also a good base for remote
attachment. You might be able to work out a reasonable scheme to just
broadcast stuff and receive commands to invoke some methods-
I need to reload the pages for example- and then the control
logic can go anywhere. While maybe "void*" is not the most OO data type,
you can pass pointers and strings and whatever in any agreed upon way :) 
Much of this stuff should be just calling existing functions and can be quite
separate although you need some hook to get the event info to send.
