I don';t know what features PC Anywhere has, as I've never used it, but if you want a simple app that can remotely connect to a clinet and display graphics card output and control keyboard and mouse movements, check out VNC. It's free, reasonably simple to install and use, and doesn't seem to use much resources on the host.
Works for me to monitor my UD cows, anyway!
Hope it works for you, Mike!

edit:Actually not sure if this will work as it needs a separate IP addy to access for each PC. Not sure if it will work though the internal net over the internet. Try it though - it is free!
