I think he was trying to refer to was Google's Big table integration which app engine uses instead of NoSQL.
Dude, what are you guys talking about?
What Big table integration?
What NoSQL?
There was a Django patch somewhere that used a thin layer to make the API "look" like the Django ORM, but IMHO it is broken in a lot of ways and you're better off using the raw App Engine API (which is in no way related to Django).
But it is a half-ass attempt, looking like some patch somebody did in an afternoon to get something working: and that was the "Google effort"?
Yes. Check out this video: http://vimeo.com/10514466
Also, the Django ORM is pretty flexibile, and the architecture just got improvements for NoSQL in 1.2.
