Thanks for the details, Diva.  I did just test this with mysql and things work fine there.

I think that it would be really good to see the sqlite migration asap, though I guess fewer people are running off master right now than has historically been the case.

I'm actually referring to the existing issue of migrating data from the old pre-ROBUST user databases to the post-ROBUST data schemas outlined on http://opensimulator.org/wiki/0.7_Planning.  This is still an open issue, right?
