I'd really like to help on this, but also hate to nag :)  Does PAS still want 
the concept of a flexible prefix?  Assuming the zbir_fixing_ids_branch 
represents the future of PAS, is there anything we can do to help move this 

If Zope3 has implemented these ideas already, I guess I could simply look at 
that.  Does anyone know if that is the case?
