[Zope] command line Zope?

I'm trying to roll out Zope for wide usage and one of the things users want already is a command line interface to Zope. At first, I thought that it was a silly request, but the more I think about it, the more I like it. In order to provide this, I need a way to run Python such that it connects to the ZODB (perhaps requiring ZEO?) and gives the user access to the database only as a specified user (with the option of manually authenticating to receive additional roles). Is this easy to do? Has it already been done? I read about importing Persistence and ZODB, but I'm clueless about setting up a user's environment in Python. Any pointers to appropriate documentation will be greatly appreciated. Thank you. --kyler
