It is totally kick ass... wait... I'm talking about VNC VNC is totally kick ass, allows you to remotely control another PC from afar!
Its pretty cool... it allowed me to freak the hell out of my one of my roommates, when I logged onto the viewer to see my computer when I was in the library once. I noticed he was using it, so I opened up Word, and started typing cryptic messages that showed up automatically on the screen at home... he swore my computer was possesed, and vowed never to use it again. But... I've yet to find a REAL practical use for it... besides e-mailing documents (that I forgot to print out from home) to myself and then printing it out wherever I am. It would be cool if you could access mp3's on a remote computer, or somethin....
Remote controlling servers of various different flavours from workstations of various different flavours...
you can access them, but from my experience it doesn't play on the remote computer's speakers. Of course, your home computer's speakers will be blasting away, probably scaring the hell out of everyone that's still at home.
