[Shotwell] Sharing a photo collection between machines

[Eric Gregory]

I know this doesn't help anyone here in the immediate term, but we've had a
ticket open on finding a way to share between machines for some time:
http://redmine.yorba.org/issues/1292

Personally I'd *love* for this feature to be in Shotwell today, but we just
haven't had the time to implement it.

One thought we had a while back was to use LDAP for sharing. That way
there's no configuration required, you just launch two Shotwell instances on
the same network and they can (optionally) share certain photos with one
another.

Patches are always gladly accepted; though to warn anyone thinking of trying
to implement this in advance, networking sharing is likely to be a
significant undertaking.
