I have used UltraVNC with some Windows boxen as it is indeed easy to setup. Really, there are a lot of similarites between the two, they are both really small, they are both "automatic quality selection based on network speed" capable, and they both come in either an installable package or the standalone exe's/libs. You can't really go wrong with either.
Thanks, I will compare features and give both a spin .
I think I saw them both at sourceforge, I always try to stick with open software when practical.
TightVNC. Small, light, fast, as configurable as you want it to be.
Use the beta, its very good. Install the hooks driver and performance will go up.
