Hi Rufus,

I'm trying to understand VDM on the way to understanding CKAN.
 * Are there any docs that explain what is going on in general terms?
 * I see you're using sqlalchemy migrate
(http://www.rufuspollock.org/2009/07/27/sqlalchemy-migrate-with-pylons/)
 - am I right in thinking that migrate handles schema migrations,
while vdm handles object versioning?
 * Have you seen this: http://code.google.com/p/django-rcsfield/

Cheers,
James
