[Zope-PTK] Area based roles?

[Monty Taylor]

Hi all. I've got an idea of something I'm trying to implement, and I'm 
wondering if the concept is of use to anyone else. 

I've got an Intranet up in PTK. (What a shock, as I'm posting here. :) ) 
I'm slowly getting people to use it for internal collaboration, et al. 
But the main things people are wanting to do are internal to their own 
department, with some overlap. So you've got:

+PTKRoot
 |
 +-Members
 | +-John
 | +-Sue
 |
 +-Marketing
 +-Technology

Say John is in Technology and Sue is in Marketing. What I want is for 
John to have Contributor rights in the context of Technology, and Sue in 
Marketing, i.e. John adds a News Item and Publishes it. It shows up in 
Technology but not Marketing. 

I thought about creating a Technolgy Item ("Release Notes") and a 
Marketing one ("Press Release") and then just having a catalog search on 
the meta-type of each in the appropriate folder's index_html and give 
them all Contributor. But that strikes me as unclean. It would be nice to 
have anyone be able to create a Press Release or Release Notes, but only 
have them published in their department's context, and merely pending in 
others.

Am I making any sense at all? Does anyone see either a need for doing 
this or a way to do it? If it requires changes to PTK core, would anyone 
be interested in those, or should I throw them in my pile of dirty little 
secrets that no one should really know exist?

Thanks,
Monty
