This looks very interesting! My mojo just arrived today and my primary transport to it was going to be DLNA from bubbleupnp.
a few thoughts on the Poly
-Will the poly's usb charging port also be usable as a source input or does the Poly need disconnected if you want to physically connect a DAP/Phone/PC?
-Surprised at only 2.4ghz wifi, this is a very congested spectrum and 2.4/5 ghz a/b/g/n/ac chips are a standard for any new wifi product release.
-If using WiFi to connect from phone/pc/whatever to the Poly, there will be challenges at enterprise wireless deployments, hotels, airports. Most of these wireless implementations use client isolation so one WiFi client cannot directly communicate with another.
-If it supports an AdHoc or WiFi direct type of a connection then this may cause internet/network reachability issues from the phone/pc
-Will it's firmware be upgradable ? (e.g. add Chromecast support, bluetooth aptx, bug fixes?) (WiFi drivers are notoriously buggy and a very fast changing technology)
-It looks like it supports higher DSD rates than the mojo, future proofing?
-Does it use the usb or toslink as transport to the mojo?
would love to hear more!
