Can't wait for these folks to enter Robodance in the next Skype mashup competition. The Robodance Skype plug-in (expected in November 2007) lets you control your robot at a distance over the Internet. Robodance:  

• Answers incoming Skype calls
• Connects the local PC to the robot via a local infrared connection
• Passes the robots video to Skype, so you see what your robot sees
• Listens for commands and translates them into signals to your robot

They show their architecture and describe the project. Sign up for the Robodance mailing list.
