Feedback for Phactory - A Database Factory for PHP Unit Tests

I released the first public version of Phactory yesterday, and I'd like to get some feedback from developers here on HN.

Phactory was born from a desire to have something like Factory Girl for my day job writing PHP. A couple of my co-workers and I have been using it for a few weeks now, and we're finding it really useful.

If you have time to give it a try, any feedback/criticism would be much appreciated.

What features would you want to see in a library like this?
