Tricky - yes, you are right that the ZODB vs. RDBMS split is the root of 
it.

What I'm trying to do is let the RDBMS manage structured, relational 
data (I am an RDBMS developer "by day"), and let my content managing 
colleague work with the content in Plone. Mapping the two together has 
been a nightmare for me - it was *extremely* easy with DTML, and 
(although I understand why it is the way to go in the longer term), it 
is only Plone's broken DTML support which is making me use ZPT now, as 
opposed to six months down the line.

I'm trying to mesh multiple pairs of concepts/entities (DTML vs. ZPT, 
ZODB vs. RDBMS, content vs. data - and the rest), and I'm finding it 
*very* heavy going and getting my concepts and entities in a twist in 
the process. I can honestly say that when ZPT came into it, this project 
simply stopped being any fun.
