Saw this on TV last night and tried it out this morning and I'm impressed. Makes for watching or controling whats going on on the other computers on the network a breeze. I have the client running on Mandrake 9.1 and the servers on the windows boxes. It will work across the internet too of course and has optimizations for lower bandwidth use if you desire. http://www.tightvnc.com/ I know this probably isn't anything new, but it does work really good.
