I have this too.

Most liekly not. MySQL is able to handle many users simultaneously, but
I don't know if digikam rereads the DB data every now and then (at least
before write). I doubt that.

You have to write a script that checks a special data flag in the
database, sets it if unset, start digikam and resets it after digikam is
finished. It at start the flag is set a message that digikam is locked
But nobody will prevent your user from starting digikam without the script.
Most secure way (at least I do it this way) is to store the data in exiv
section of the photos. As I am the only one who uses raw format for now
this is no real limitation (I don't let digikam write exiv to my raw
photo). And at least my digikam recognises changes on the photos
As I want to be able to use digikam without a net (with my local
collections) I still use sqlite database.
