Hi there, I'd like to have a mapping of users to accounts, and then have users directed to a namespace corresponding to their account. Having looked at the appengine_config.py from the suggested example, there appear to be a few suggested ways to determine what the namespace ought to be, i.e. Server name Google Apps Domain Cookie I...
