failproof,
The issue of direct-sunlight is going to be a problem. On one hand, my new stake center came with 7 Projectors (4 of them Epson MovieMate DVD/Projectors w/sound) on the other newer buildings are increasingly utilizing natural light, we have an outer wall and an inner wall. If you can strategically designate rooms as 'Seminary' Rooms they will all come with the 'darkening panels' behind the curtains. That was helpful... for other situations, we've found that the Televisions are fine in direct sunlight.
Churches are already known as easy targets with very cool Audio/Video equipment, game rooms, etc... Churches in general already have this problem, this is true, and may require us to think a bit more about the security, but I believe it is relatively low on the issues to worry about list. As I stated above, our new building came with a bunch of technology I'd never seen in a building before, including wireless, projectors, tv's etc.... transition has happened....
dannykos,
I believe this will naturally work itself out, there will be members of a ward who will bring in their own stuff to supplement, and as the needs arise we'll either work with FM to purchase or take some budget one year. I'd so much rather have 2 additional 32in tv's than some of the other areas we spend out of our budgets.... hey, you could even say the tv's are equipment for girls camp and have a fund raiser... then just choose to store them every year in the materials center? That's still technically within the handbook right?
