@alasta - now that I have had a proper look at the Bose Soundtouch Link Adaptor I realised it covered the majority of my requirements - sans remote, but can operate via my phone so that is good enough for me.  I saw this device when it first came out and for some strange reason thought it was just a very expensive bluetooth adaptor...

 

Anyway I put my money where my mouth was and bought one yesterday.  Pricespy quickly showed me that this $299 device was on special at AV World for only $139 so the purchase was a no brainer.  I now have it set up and running perfectly.  Considering getting a second one this weekend.

 

Thanks again for your help and for everyone else's input (even the Bose trolls ;))
