It would be pretty straight-forward (although I haven't done it) to do a non-Django version of xact(); you'd probably just pass the connection object in as a parameter to the decorator.
I've noticed that in real life the savepoint functionality is not used all that much, but it does provide a nice consistency to the implied semantics of the decorator, and it's great when you actually do need it.
