From what I've read, the Google appengine code runs on Google servers,
period. Does no one else have any concern about the scope and size of
Google? Regardless of the supposed altruism of Google's founders, the
larger they get, and the more you throw your lot in with them, the more
you will be forced to play their game their way. Having dealt with Google
several times, I can attest that they are not the most easy company to
deal with. While Rietveld seems to be a kewl tool, it bothers me that it
can't be hosted on my local server. Maybe it's just me.
