I\'m in the process of starting a new project on App Engine and Brandon\'s advice made me think.
Many features of Django don\'t work on Google App Engine: the ad
At the time of writing most of the django features been ported over to GAE with the help Google Appengine Patch project.
The main which wasn't yet is Django's model support, you have to use GAE db models. But it doesn't hurt that much.
Just get Appengine-Patch and try it.
