Show HN: GAE/Bingo, A/Bingo split testing for App Engine & Khan Academy

We just open sourced GAE/Bingo, a re-imagining of patio11's A/Bingo for use in App Engine (w/ his approval). The lib was built for Khan Academy, where it's currently serving up A/B tests at a few hundred requests/second w/ minimal page load drag.

It should get anyone on App Engine (python) up and running and A/B testing in minutes -- if you have trouble please let me know. Does its best to maintain identities as users transition from anonymous to logged-in, persists experiment results to the datastore in the background, etc.
