It sounds like your requirements are evolving, but the solution to your original idea would be sonus using the hub connected to the receiver line out, or wisa speakers with a hub connected to the receiver. I don't think any of these work out cheap, and they probably have some support complexities, but they give you wireless speakers with a traditional front end. Personaly I'd try and make what you have already got work, as I've never had to remotely reboot speaker cable to get it working again.
