I would rather do it the other way around - first look for the 'db'
argument.  I would also update the catalyst controller to put the
schema on the form stash as 'db' - this is just like the advice people
give on the Catalyst mailing list about using context in the model -
don't just insert the whole context into the model - filter the things
that you'll need.

I would not bother with that - in fact what is the Catalyst model for
DBIC is also a DBIC schema - so you should not use schema to mean the
resultset.  You can have another argument for the resultset (by
default ucfirst( form_name ) can be used as the resultset name).

By the way there is also another question - how do you plan to extend
the model stuff to include other models (like LDAP)?  I think you need
another argument that would specify the model to be used and load the
model conditionally.
