I'm not sure that GAE is the ideal environment to run Django in - the whole reason it scales is because it enforces a certain way of doing things (nonrelational datastore, no long-running processes, no local storage).<p>General Django PaaS will probably be 'nicer' with the various less-restricted options that are springing up (be that mine, ep.io, or others, like djangy, gondor.io, apphosted, or the several others I forget), since those tend to lessen up on the "it must scale" aspect and focus more on making the 99% majority of sites (i.e. medium sized or smaller) work well.
