I was wondering if anyone has experience with this...

What I want is something like a VNC experience, but that allows the person sitting at the host machine to work uninterrupted. The host machine is Win98. I have seen virtual desktop hacks done on Win98 and thought if that can be done, maybe a terminal server-type service can also be loaded. Is anyone familiar with any software that can do this? Free would be best, but cheap shareware is OK too. TIA.
