You can't. It's the "primary key" of the kind. The objects are fetched

It's a hard choice, you really have to analyze per case.
If only it got cheaper, it'd be a lot more suited to a wider range of
projects.

while it definitely should.

I still think you are basing your comparsion on assumptions, ones yet to be
proved.
Its almost certainly better to wait until the promised price comparisons are
available before jumping to conclusions.

If you own the second system, you can build a protocol where your appengine
system saves the blob to blobstore, notifies the second system that a job is
ready, handing it a key.
You then have the second system fetch the blob off the appengine.

I hope the GAE team corrects me if I'm wrong, but I wouldn't worry too
