Matt: There's nothing wrong with your original suggestion that Mike consider 802.11b. Mike's customer's A/V network only needs minimal security, actually IT doesn't need much security at all. As I said if the A/V network "sees" the same wire as the customer's home computer, there needs to be some isolation.(Assuming the customer has anything he's worried about on his personal computer.)

Some people just assume that since full security measures aren't mentioned, they don't exist. A typical A/V network is hardly deserving of the security attention we might give a production IT Enterprise environment.

Let me plagarize five words and one numerical value from Matt, and then a complete sentence from Mike:

"As far as 70 Volt goes" it should be FINE for music that is only meant to "lilt around the ears" whilst enjoying "a walking path installed around the perimeter, which is a little over a mile around."

(I wanted to come clean on the plagarism B-4 billybobb busts me.)
