Um... you just said basically the same thing I did. :-)  I suppose I was 
too terse.

Hmm, that may be doable.  Nifty!

It's a piece of Zope infrastructure that isn't there yet.  In fact 
yesterday I spent a lot of time trying to find a nice way to achieve 
transparent indexing.  I even modified cPersistence.c to try out an idea. 
I'm sure there's a way to do it right but we haven't found it yet.
