Ok, that is 373 lines of Ruby code... :)

Currently, yes. I have actually started looking at DRb, but not
had the time to figure it out, yet. But it is definitely the way to go.

That should not be too difficult. It could even be some kind of
"default" mode if a database connection is not available. Will
think about it a bit... :)
