I've resurrected the MDB repo on gitorious.org. Some people were complaining that they didn't want to pull down the entire OpenLDAP.git just to get the MDB source code.
Also, on an unrelated note, I'll be talking in Dublin tonight at an Open Source meet'n'greet event. May rustle up some new developers, ya never know.
