Ahhh that makes more sense

How about justing using an Audio Distribution Amp, I did a little Googling and this came up pretty quick...

I'm sure you could find something in the US that does this.

As for getting the signals to the TV's I'd use Audio over Cat5 boxes similar to these...

I would expect that over longer distances Cat5 would be both cost effective and not degrade the signal too much.

Edit - Or go for an OTT one box solution... http://www.futureshop.co.uk/atlona-1x10-...r-7-p-4532.html

Edit again - A more cost effective solution... http://www.pixels.uk.com/products/DataBay/AVE300.html
