A pair of DBS dishes with a bi-quad antenna mounted in place of the feedhorn, fed by WRT-54G routers with DD-WRT firmware to tweak the power and turn off one antenna port will be perfect for this application. You can either flip the dish so the feed is on top, or mount the pole so it's horizontal (or at a 45* angle) to get the proper look angle for the dish.
