Not quite the same thing but Barrier and Synergy can make two computers share a mouse and keyboard multi monitor style over a network (ie, you they switch when you mouse over the edge of one screen).

Tried it. Couldn't get it to work reliable (something with it getting stuck to one or the other? I forgot). Latency was noticeable but OKish.

Thanks for the suggestion tho.
