I think that's the dumb part though. If you get one user per hour for 12 hours a day, you're still overflowing the "6.5 hour limit" (unless I'm misunderstanding everything).

I'd love to use GAE for the reproduceability of dev environment, but lock in, 10x+ price increases and a VERY obtuse (not honest) explanations of how pricing is measured and billed makes EC2 look much better. I'll need EC2 anyway since you can't run arbitrary binaries (ie: PDF conversion) on GAE.
