GAE is ideal for nano web apps. I wrote an HTML5 Canvas Plasma Benchmark using GAE/P: http://speed.okaq.com/ http://speed.okaq.com/ It clocks in under 10kB compressed, is very fast, very accurate and I use it to test devices all the time. Under current quotas, I'm able to serve ~200k users per day at no cost and am actively developing 2 more nano web tools. The development environment is certainly restrictive, but the risk for web app prototyping is absolutely minimal.
