Alexander,
Until a future release of Django that supports non relational
databases via the Django ORM, and Google support for such a release,
the Pinax core developers probably won't consider trying to make Pinax
work in GAPE.
Pinax has certainly been used in high volume sites, both in and out of
the cloud. The largest I know of is the Richmond Sentinel which has
nearly 1 million hits a day.
Getting Pinax to run on a large scale is just like getting core Django
to run on a large scale.
