Hello,

I'm wondering if your need can be addressed by the "ID generator" patch 
posted by Roché Compaan (see 
http://mail.zope.org/pipermail/zodb-dev/2003-August/005690.html).  I 
think it is a more general solution.

I would like to see some form of Roché's idea put into ZODB proper, and 
would be willing to help with the maintenance, documentation, and testing.

-John
