I wish there was a way to play with it initially without giving up my email. I hate getting automated 'haven't seen you for a while' app-spam. It's pretty standard though, so maybe it's just me.

I'm using App Engine too; seems to be a good choice. And oddly, the performance stats for Python vs. Java seem indistinguishable. I would have thought Java would pull ahead on repetitive server-like tasks.

I love one-click demo too, and hopefully I can add it later. About Java vs. Python, from my experience datastore RPC are often the bottleneck anyway.
