DJango Appengine Bforms

Question

I am trying to understand how Django and Appengine work together?

1. First, question: Is this a good team? Experience, what is possible and what not, would be great.

2. I also read some modules like auth, admin wont work. But the article is rather old, so maybe there is an update.

3. And in that tutorial one has to import bforms.

What is that? Django Module? Appengine? Python? Bigtable?

1. How is Bigtable different from regular SQL, MySQL?

Thanks
