Well, to convert video to a format that can play on the iPad is not that big a deal.
For my purposes is a notch more complicated because I'm trying to serve a live signal to the iPad, or stream directly into the unit. The Wi-Fi/Bluetooth may be the way to go, but for that to work I need two pieces:
1. A camera and software that can send a signal to a server
2. A blackbox that can received and stream that signal into the iPad
Pretty much a Netflix type connection, I just need to figure out who makes 1 and 2.
