I've never done it before but here's my first guess.

RTI does not have 2-way feedback yet. If you use an RTI T4 which lets you stream video to it, you can look at the picture off the PC to see whats happening and control it that way. To stream video wirelessly you just need an piece that i think panasonic makes that takes video and makes it into a webpage that you can browse to and view in your network. You then just set up a browser on the T4 to look at that address.
