So, what's VNC? Virtual Network Computing. I use it at work a lot (it's how I can monitor student machines while they're working on computers. Embarrassed my cousin Chris one time by projecting his screen on the board during physics one day. Heh heh, yes, I am evil.) It basically lets you run another machine as if you were on it rather than on your own. It's a little sluggish in running, but for running playlists or double checking a certain service is running, it's wonderful. I use TightVNC as my program of choice. It's the program I picked at work to be the server program, however, I view multiple screens with VNCon.
Anyhoo, there ya go.
ETA: Darn LJ and their lack of Flash support... I guess if you want to listen to my Last.FM station, you'll have to take the link above. :-)
