All the Python ones other than GAE are in different beta stages. I hope one of them becomes as good as Heroku, Google would be incredibly tempted to buy something like that. GAE seems designed to assimilate apps into Google rather than to serve the needs of developers.
I remember reading somewhere that Google was trying to get pure Django code to work on App Engine (with limited support for queries, of course), and I am very interested to see how that goes. If that happens, (and App Engine gets SSL and an SLA), App Engine will probably come out on top.
At the moment, Google only has "bulk datastore import/export tool" on their roadmap, which implies that they are trying to reduce their lock-in at least a little.

But the competition never hurts.

Looks like you technically can run pure Django with some limitations.
