You can easily detect requests coming from this app. The User-Agent header

I can't seem to find any documentations about auto generated numeric keys
on whether the values are guessable or not. I want to use the key as an
order number to give to the user, so I need something that is not
guessable.
I'm using JDO with these annotations in the primary key field
@Prim
The numeric id's are sparsely generated unless you preallocate ranges, but
they are in a finite range, so in theory some one can guess them.
Maybe you should hash them (along with some other data) and provide that
instead, then store the hash and use that to lookup the id.

Yes, but SendGrid is 5-10 times as expensive as Appengine, per email. If
