I'm certainly not opposed to it if it can be done in a clean fashion.

It is not going to be trivial at least.  One problem is that in the
current code, each location (URI) is required to map to exactly one
RhythmDBEntry (which represents a song or internet radio station).  
You could get around this by creating your own URL scheme for accessing
chunks of the file, e.g.:

file:///media/music/myfile.flac#cuesheet1

That code is completely revamped in the latest sources, and I strongly
suggest you work from those :)

In the new sources the node is created and the metadata set at the same
time (in one atomic chunk).

So you'll need to have flac-stream-info-impl.c (which reads metadata)
understand your URL scheme, and monkey-media-player-gst-tmp.c will also
need to parse it in order to seek to the correct location.
