VNC

I actually found the NX information in the comments for this SlashDot article.

I use RealVNC extensively at work, since I am an IT Guy, and it’s easier to fix the little problems if I can see a user’s screen, and it’s more likely that I’ll get to see the screen if I can just jump onto the screen remotely. However, I find that RealVNC often isn’t quite responsive enough for my liking, and it interacts poorly with our new company-wide business software (which seems to run in a MacOS 7 emulator, messing up VNC screen refreshes like crazy) so I’ll be trying out these other flavors.

TightVNC interests me because it compresses the framebuffer information, which should improve speed in general. UltraVNC installs its own virtual video driver, so it should get every change in every window. (TightVNC also seems to have this feature starting up.) It also supports file transfer. If it turns out that either of these products has a superset of the other’s features, I am definitely switching over, especially since each flavor is backwards-compatible so that I can still use my Macintosh VNC implementations.

If I find anything conclusive, I’m likely to amend this post and bump it. Just so you’re warned.
