THX, thanks for the input. I checked out the Xantech stuff - pretty slick.

However, after checking out prices of emitters, extra receivers, etc, it makes more sense to expand the A-bus. After talking to some Russound guys, it's not that much extra, and gives me a consistent system across the house. There are cheaper hubs available that I wasn't aware of for expansion. Tried it out over the weekend and it's working well. Have to order the extra hardware to replace the units I borrowed from elsewhere in the house.
