Is there a way to view my Macbook Pro running Leopard on a PC remotely on a different network (that is, different router, different external IP addresses for both). Me and a friend are doing a group project and it would be easier if he could see my screen at the same time, but he is on a PC on a different network. Is there some sort of Mac or Windows app that allows him to view my Macbook Pro? Thanks. I know that there is the Screen Share option in Leopard but im not sure how he can view it on his PC side.
