Multiple Mouse Pointers - Mac Os X

This project is simple in theory to someone with a proper background in this field. Your job is to make it so when two mice are connected to a Mac Os X Computer that 'two separate' mouse pointers (cursors) appear on the screen. ? So one person can be doing there own thing say in another monitor or section of the window in a separate application (or the same) at the same time as someone else is doing there own separate thing. Currently if you plug in 2 mice, if one person moves a mouse they share the same cursor which is unfortunate. This is very useful for people that have multiple monitors like myself, if I want a colleague to view information for me and we only have that one computer available. ? There appears to be a good demand for this also. ## Deliverables There will also need to be a license key system involved for users that purchase this program later. ? The program will sell for $19.95 =).
