[Shotwell] mysql/postgresql as backend?

Yes I can see that this ticket (D-Bus) would solve some issues.
But not the one with a family and a number of computers.
For instance, I am updating the photos from my laptop (connected to our
file server), while my wife is looking at the old photos (again, through
our file server) as well as possible publishing some photos or modifying
some tags/ratings here and there.
This would not be possible with sqlite as far as I am aware (single
program who reads), but very possible with a sql backbone.
Perhaps a function that informs all other connected clients to re-read
part/all of the database?
While on the subject of family :) Perhaps a locking feature, to ensure
children can not modify any photos/tags :)
