Guido mentioned at Stanford that some Google developers are starting
to use GAE for various things, so "largely based" could eventually be
true (for some services), but is it true now?

For example, Google search predates Bigtable and GFS.  Bigtable may be
used now for crawl infrastructure, but I doubt that it's used to serve
queries.  I very much doubt that any other search code is shared by
GAE.

Other google apps are built on Bigtable.  Picasa may be the source of
the PIL infrastructure (PIL requests are farmed out to a photo-manip
server farm).

Beyond that, what parts of GAE do you think reuse existing google
software?
