Thanks very much. I did a little more research after reading your reply.
I think I will dive in and try a flavor of PC client (perhaps TightVNC) to OSXvnc server and hope the speed is acceptable and the hassles are fewer - once I get past the installs and firewall configs.
Greatly appreciate your help.
Some of the problems I've seen with various VNC client/server combinations include firewall issues, slow connections, and just plain refusing to connect. Watch the log files in Console.app in the Utilities for error messages. Good luck.
