After a little searching around (OK, a lot of searching) I’ve found a solution to help kick music around throughout the homestead with only a little fussing.  The equation works like this:

Roku SoundBridge + SlimServer 6.2.1 + SoftSqueeze PC client + MP3s = whole house synchronized* audio

I have to put the * caveat in because the Roku really doesn’t handle sync terrifically.  But it does it well enough to walk around the house and hear the same song everywhere at nearly the same time.  Considering the extra cash outlay was zero, its not a bad solution.

Now, when am I going to get some more of these devices?
