Very nice, that MB is going DLNA / UPNP
The most important feature for MB is (I think) the distribution of music to clients, witch follows strictly the UPNP / DLNA standard.
So, - I think -Squeezeboxes are outside - good clients, but proprietary and nearly dead in support (I donĀ“t understand Logitech)
For me, the choice is using High-End Fidelity Equipment and different destinations, i.E. the Network Receiver in Living Room and his speakers
My Library is on a Synology NAS, MB has great features to find, sort and visualize all my music, and now I hope of high Level sound output from Yamaha....
Good luck und success for implementation and excuse my bad English
