Mouse moves over network

I'll try this one again I think...

I've got my two machines on my desk, networked, and I'd love to be able to use just the one keyboard and mouse for both of them, so can anyone give me any ideas where to start writing some kind of app to do something like this?

Cheers, yer all bootiful...

Wot? Don't nobody know the answer? Where's all you brainy blokes today?

Hmm, I think I'll reply to my post again. Would anyone else care to join in and show how clever they are? (no)
