I'm looking for a product or set of technologies that can resolve an issue I'm looking into. At the dojo I work at, we're looking to setup a skype setup so that a couple of the students who are not local can continue to participate. I'd like to have some sort of camera that feeds into a tv that we have setup in the dojo. Its an older flatscreen of that matters. The usually webcams don't seem to help me out as I couldn't find a USB port on the TV. Any suggestions on how to get the ball rolling and perhaps get my mind wrapped around what our options are, would be appreciated.
