What I'm talking about involves more than caching; I'm looking for a
way to relate data arbitrarily. 

By putting tag/filename data into a sqlite database, which is
essentially a single file with no daemon or anything, you can generate
smart playlists on the fly, like the examples I suggested. Doing that
via cache files doesn't make sense, first, because it requires data
that isn't stored in the MP3/video, but also because it needs to
relate things. A list of files is not related, but "songs with
year=2000" is related.

I've already started playing around with sqlite and it's very easy to
use. What might be a good idea would be coming up with a way for a
piece of code to inheret mmpython's base caching class, and override
the storage part.
