If so, it could be plain awesome. I'm imagining a server in closet that aggregates music collections from various sources and provides uniform interface to play it anywhere network-accessible.

Right now, at work, I simply NFS mount my home music library, and then sync my mpd tag cache over periodically. This works while I'm in one location, at work, but would not work on my cell phone; I don't have a network protocol that would survive it, and MPD has no real support for high-latency filesystems (it doesn't know to go fetching the next file in advance, nor does it know to go cache a few megabytes -- or the next few songs -- in case the data link goes away).
Mopidy's extension support is pretty exciting, then! It seems like it should be relatively possible to concoct a 'mopidy.remote' extension that knows how to do these things, and the corresponding server-side for a Mopidy instance running at home.
Have you folks thought of this sort of use case? Am I about to reinvent the wheel?
