Hey,

I think there are two cases where people typically deal with local
configuration:
* setting up local utilities (for authentication, the catalog,
application-specific configuration storage + UI)
* writing tests that involve local utilities. (a more advanced case, but
still quite common)

I don't think "hosting multiple web sites with different configs in the
same application" is the only use case.
* the catalog. This can be done using a global component that somehow
stuffs information in the ZODB, but there are no common patterns for
this that people can follow, so local utilities are currently easier to use.
* often it is nice to have application configuration to have a user
interface, so that end users can configure aspects of the application.
This may be filling in an email address or customizing a template or
adding a user, etc. Local utilities are a nice solution for this, even
if there is just a single application installed.

My goals are:
* I do care about local component configuration
* I'm a simple person and want to make my life easier
* I want to be able to write and test local utilities without having to
depend on zope.site for my testing (right now I have a hacked up version
that I just copy and paste). An example of the hacked up version of
site management is here:
http://svn.zope.org/hurry.custom/trunk/src/hurry/custom/testing.py?rev=99648&view=auto
And I'd like to put that code somewhere proper.
* I'd like to change the dependency structure so that a minor dependency
on site management doesn't require a package to pull in zope.container
(which pulls in quite a bit itself)
Regards,
Martijn
P.S. As of this point I'm dropping my proposal to rename anything to
anything. Let's indeed focus on the wider discussion (as indicated by
Roger and Jim)
