What do you do with entirely new methods?

<cw>
As in ZClass method? Add them using the normal manage_add* stuff. Utility.py
in Squishdot has methods to do this.

Installing a python product should be ok, but I'd like to automate
the installation of the external method because none of the users
currently have management rights.

Well, you could write a product that does monkey patching and updating on
initialisation and the delete itself off the filesystem ;-)
