Hi, 
I was inspired by this thread:
http://groups.google.com/group/ibm_db/browse_thread/thread/18d3eec89eca7e7b
so I send you Django adapter (alpha) based on PyDB2. 

This is based on Django 0.96 release. I needed django working on db2 and
did adapter by looking at code of other adapters. Module is functional in
my environment, but ... Didn't runned django tests against db2 module, so
probably lot of problems still exist.

In attachment you'll find:
 - db2 folder from django.db.backends folder
 - django_db2_adapter_0.96.diff - diff agains slightly modified django 0.96
release

I'm very glad that this project exists, finally python/sqlalchemy have
proper db2 driver. I'm hoping that you'll use this work (or not ;) ), and 
fill the gap for db2-pythonists - django-db2 adapter. Continue with the
good work. 

Regards, 
Robert
