Hi Jim,

perhaps we can discuss this on zope3-dev.

We have to totaly hide this part and offer a different concept.
Of corse the normal registration will be available too. 

I propose to add something like a policy. A policy should register
a utility. This means we can add policies via ZCML and the user can 
only process this policy which registers the utility in a predefind 

Then we can provide a task like. "register PAU" and everything gets
registred. There could also be a different policy like:
"register PAU with initial principal folder" etc.

A ZCML directive could look like:

    name="Add PAU with principal Folder"

Then we can offer adding utilities via this policies.

If somebody likes to register a utility in a different way, he can 
add own policies for a utility.

I use this pattern in a own registry in a different usecase. It makes
it very simple for anduser and even me to register components in a 
registry. And you don't have to know every little about the registration

What do yo think about that? Any other ideas?
