Hello,
might interest several of us:
Joe Robbins at Bawtry.net has been working for some times on split-keys.
I'm in touch with him and  he has recentry sent me his patches for OC 
1.1 split keys support.
I'm helping him to test them (bdb) on my programs. From what I've seen 
so far he's close to achieving the result.
