I suppose, you would like to do the server definition thru something 
like paste.deploy (allowing us to let the assembly currently done by the 
two main programs be done generically).

What would the application definition be? Still ZConfig?

(Note that in my original reply to ChrisW, I tried to be pragmatic. Of 
course, if ChrisW has the resources to go into this refactoring, by all 
means, let's do it).

In order to implement a simpler security mechanism for grok, we had to 
re-implement every single publication (though of course subclassing was 
still possible, but we had to create a new variant of every publication 
class). That shouldn't be necessary.

I think the ZConfig argument was largely due to misunderstandings. I 
would be surprised if people really cared whether to Zope used 
ConfigParser or ZConfig (except Fred, perhaps ;))
