Im just playing around with it with two XP Pro machines. When I log onto other computer it logs the current user out...Ive searched around the net and havent found anything. Anyone know of a way to make it not log them out. It doesnt sound like it could be done...way too much processing and what not IMO, but who knows.

We use VNC (http://www.realvnc.com/).

There is an option called "shared session" which makes it possible for two people to view a computer at the same time.

Hm...well that looks like it might do what I want, thanks. I'll have to play with it over the weekend sometime.
