[mythtv] mythmusic sync'd streaming

[Chris Petersen]

a friend of mine got the new Squeezebox from http://slimdevices.com/ for
christmas, and had mentioned that it's capable of playing in sync'd mode
if you have more than one device (somehow you put it into "sync" mode
and the remote controls all devices, which are able to maintain sound
sync with each other).  I know that this "streaming server" idea has
been talked about for mythmusic, and so I thought I'd mention this in
hope that the slim devices code may be of help (you might also want to
look at something like ntp, which could be used to keep system clocks in
perfect sync between front/back ends).
