wow this is all great stuff, it sounds like my concerns are overblown.
Honestly after reviewing all the features of the GAE api i was deeply
concerned about any DAL that supports SQL being of use on GAE but your

I am creating a file (pdf actually) that is being generating in

I believe there is no overhead issue. I have been able to move all of
the SQL tables into a module
so that they persist across requests. And in the module, I wrapped the
table creates in an if() statement
which checks to see if the table already exists.
I changed db.py to just have wrapper methods

I'm not sweating over it, but this is still important for me because
my client may later want their GAE app migrated to a personal server.
Also I don't want to be locked into GAE
I've also got a need to support uploading multiple files (perhaps
