Sounds cool.  Great to see some App Engine examples.

I'll take the easy one:

The cache is write-back (I think), so normally you should only have an
issue if you're doing writes and reads from different clients.  In
your case, only if you write from AppEngine, then read from the
browser.  If this is the case, use the touch API from the browser to
get its "last write" cookie reset.
