TeamViewer – Free Desktop Sharing and Remote Control:
Instantly take control over a computer anywhere on the Internet, even through firewalls. No installation required, just use it fast and secure.
Nice nice nice nice nice – I really could have used this earlier today trying to help troubleshoot a problem with someone’s email setup 1000 miles away. (Sorry Smythe!)
Also, there is this: Schnitz Remote for OS X remote control. The person wanting help contacts the helper.
