Multiple Remote Users working on a single desktop with many mouse pointers

Question

I'd like to try and build something like this using C#

http://www.multimouse.com

I've heard of the MultiPoint Mouse SDK and it seems to be more geared toward physical mice on the PC you're looking to control. I was thinking maybe I could,

"at a remote users request, create a virtual mouse on the "Server" PC, and then translate positioning and events to the MultiPoint code?"

Anyone have any suggestions on where to get started with this? Or considerations?
