Hey. That USED to be the case that app engine required substantial rework. However there are now no-sql libraries to make normal Django work. I also think there was a summer of code project that might add no-sql support to the django core eventually.

You should search around stackoverflow.com or hit up the #django on freenode IRC. My advice is you need to look into how the django community is deploying to app engine more closely.

edit: Dug through my bookmarks, this is what you need: http://www.allbuttonspressed.com/projects/djangoappengine
