Competing with Google while running on Google App Engine
eklitzke: I wouldn't worry about it too much. If you consider Google Apps, Google is already hosting email, documents, spreadsheets, etc. for a lot of businesses, including many that compete with Google in one way or another (after all, Google has an awful lot of products). Furthermore, Google is a pretty large organization, so it seems like it would be risky for them to try to spy on you (since it would involve a number of people in at least two or three departments). If they got caught doing this, it would be pretty damaging to GAE.I think a more interesting consideration is, how does this affect the prospects for your company to be acquired at a future date (assuming you're interested in selling out)? Presumably hosting on GAE would make your company an easier acquisition target for Google (since you've already bought into their infrastructure). Presumably it would also make you less attractive to a lot of other companies who might be competing with Google, since you're basically going to be stuck on the GAE platform, and those companies may be more paranoid.Just my 2c.
