Well, I'm supposed to be moving into a python dev position @ work soon
and they have actually got quite good object <-> relational mappings
working, but I don't have access to that code yet, and don't know if
i'll even be able to reuse it in my own projects..

and once again, it requires three separate objects - an account, a
contact, and an account_view..

I think I'll poke around with t.enterprise a bit more and see if there's
hope for me there..
