This might be a really silly idea, but heh: what about using xattr for
f-spot data? As far as I understand it, xattr is designd to solve the
metadata problem. On a practical scale, of course, xattr is not always
available, performance, etc. But since the filesystem seems to be a
decent point of seperation... To retain the current f-spot code, maybe
only a reference into the f-spot DB would be necessary, and beagle
then indexes that when it's available. Update notification -- does
inotify respond to xattr changes? Or maybe just watch the fspot DB and
reindex?

It's just a complete pie in the sky, and related to my wondering why
xattr isn't used more extensively in the 'nix world.
