That's probably the easiest way to go, but the video guys claim they need
6mbps and it's good to have some headroom.  I would think 8mbps would be a
minimum speed to get reliable, sustained 6mbps throughput.

Hmm, interesting.  I'll give them a call.  Right now we're looking at a
couple of options, one of which is 6 leased T1 lines bonded together.  I
would hope the wireless carriers can beat that price... :)  Actually, I've
heard that a leased fiber cable is about the same as 2 leased T1 lines
(remember we're talking non-profit pricing here) but the installation is
relatively expensive.  Fiber should allow streaming HD at insane bitrates.

Well, that's another conversation.  The video guys are eyeing an embedded
solution which involves a pair of SDI to TCP/IP converter boxes.  This is
where the 6mbps number comes from.  The tech guys (including myself) are
convinced that a software solution would give more options and could beat
6mbps.  Any solution will have to be at least DVD quality.  The video is
shown on 30-foot and 45-foot screens.  I don't know the projector resolution
off the top of my head though.
