James, what is puzzling to me is why you would want to use USB when you have a bridge. What you should do is this. Create a directory on your NAS which stores all your music(say flacs). Install PS audio's eLyric or somthing like assetUpNp on a PC on your network. If you use assetUpNp you also need something like media monkey to do tagging and retrieve cover art. You can also use JRiver, which I believe also streams to the PWD bridge using DLNA.
You point your music server / UpNP server to the directory on your NAS. Next you load eLyric on your iPhone. You select the PWD as your media rendered and the UpNp server as your library, and you're in business. ELyric will allow you to stream radio stations from the internet. If you download a track for HD tracks, you simply copy it into your directory on the NAS.
This setup allow you to exactly what you want to do, will be the cheapest and sound the best. Forget USB!!! Not sure about MOG streaming though. YOu can ask on the PS audio site and I'm sure they can answer this question. You would have to do this using the eLyric iPhone application.
Even if the bridge + eLyric does not support MOG, you are still better off streaming flacs to the bridge over your network and connect an el cheapo PC to the PWD USB port separately for MOG streaming.
