Multimedia in the Sunday school room

I want to be able to project, to hook up a computer, to watch, to listen and to teach. I think I might need a nice lcd tv, a projector and an easy way for anyone with a laptop to be able to hook up quickly. Then I have to find a good place to lock it up so that people can get it when needed but won’t lose the remote. What systems are you using in your church? Portability is key. I’m thinking the typical “media cart” since I have one alreay paid for. Now just to find someone to donate a couple grand to get good gear. Oh, and I also want plenty of UM Hymnals, so that’s probably another $500. Too bad I don’t play the lottery.
