Hi John, I think Eli had an excellent question. If you guys are not a .Net shop, or are just stronger in, or prefer, Python maybe switching would make sense.
One of your comments caught my eye: "10 times more complex, with more varied user engagement." I am not 100% sure what that statement really means; but, if it means you want to be able to interact with your data in more 'dynamic' ways I would suggest you to carefully evaluate the datastore's limitations. There are good techniques for interacting with data on App Engine, but to be feasible they typically require either 1) pre-computation (ie the developers expected "the question") or 2) offline / background processing. That said, I think AE is a really cool platform -- it provides you with a very unique and powerful environment.
