bluetooth expereince (Score 1)

i did this in a boardroom at my office.. .

bluetooth form 30 feet worked OK but it was sketchy.. signal would drop in and out. not too usable.

so i got one of these:

and hung the bluetooth receiver in the center of the room. USB over cat5 goes a long way and you can hide the cables well.
