whoa, wait up there!  Either you have a registry or you don't.  If your 
model is ok with long term inaccuracy due to data loss, data rot, or 
cruft accumulation, then the question needs to be asked whether you 
ought to be running a registry to start with.  The whole point of a 
registry is that it provides some level of comfort about resource 
registration accuracy.
