Just another update. I had a spare 2Bay ReadyNAS Duo with a 2 TB( I had earlier planned to sell, but luckily had loaned it to a friend) but when my son who lives in the US was visiting here last month, got it configured for his SB Touch. I loaded LMS, put in some content, and lo and behold it is now up and running in the US. I think this is a great audio server, and with additional bays can be a great media server, (as well as a back up place.)
The NAS can also play music using your laptop, with the Sq Box software accessing the NAS wirelessly.
