admittedly, it does.. I'm embarrassed to admit that I'm currently using
a pretty lame db access method..

The Python Cookbook outlines a LazyDB class (aptly named at that) which
implemens Connection, Record and RecordSet objects (though I honestly
don't see why it couldn't be done with a list of Records).. 

As it is implemented, it doesn't seem feasible to subclass the Record
object, which means I can't implement objects for each of my tables..

I've got a few more fields in the contact table, but we can work with id
and name..

If you check the other reply to my post, I tried the create view method
and it seems like it will work, but still makes for messy integration
with row, since i'll have to define three rows - one for accounts, one
for contacts, and one for the integrated view (although honestly, the
account table will rarely be accessed without the full view).

Thanks!
