I ask how big because a meeting room looks kind of silly if it's significantly out of scale with the number of attendees; this room seats about twenty people around the central table, with probably as many chairs around the walls. If you can get at least ten people into the room, though, it shouldn't look too cavernous, plus there will be plenty of room for the cameraperson(s).

As it happens, I *do* have "one of those new-fangled cell-phone cameras", but I would no more use it to take a picture than I would use (M. tells me I should not finish this sentence. :) )

I'll haul my DSLR in to work and shoot a couple of frames. :)
