The way I understand it, GAE spins up and spins down servers to meet
the needs of an app - or even just because it feels like it. What
effects does this have on the *persistent* scopes (sorry Sean I know
you hate them being called that :) like application and session? More
specifically:

- Are those scopes synchronized between machines? That is, could
application.myvariable return different values depending on which
machine it pulls it from? What about session scope?
- Will the app scope be reset quite often as machines spin up and down?
- Will it be the recommendation of openbd to favor memcached instead
of those scopes?

Which leads me to my next question: what's the status and plans for
memcached integration? Will it be transparently linked to the app
scope, or will there be a specific set of functions to interact with
it? For now, should I just use the datastore as my cache instead of
app scope, session scope or memcached?

Thanks,
Baz
