The all of the "standard" parts of Lift work on GAE except Comet and Mapper.
 Comet doesn't work because of the ban in GAE of creating threads (Actors)
and Mapper doesn't work because there's no JDBC source on GAE.

With that being said, I personally think GAE is the worst of all possible
worlds.  GAE has a severely limited run-time (the idea of not being able to
have asynchronous messages is a huge limitation).  BigTable is good for a
limited number of things, but even the most trivial apps (e.g., yet another
Twitter Clone) is going to require a relational database or some other model
beyond what BigTable offers.

GAE nominally scales well, but if you're moving to Twitter-like traffic,
you're not going to want to be tied to Google's infrastructure... it's just
too scaring from a business perspective.

For $10/mo, you can rent a slice at SliceHost or prgmr.com that will run a
nice app and allow it to scale to hundreds or maybe thousands of users.

So, if you have an actual need for Lift on GAE for an actual production site
and Lift is not offering a particular something you need, please tell us
about it and we'll see about scheduling a fix.

Thanks,

David
