You can't get it perfect, realistically.  There could always be two 
parties that want to call their module some name.  I mean, you could 
number modules based on the cardinal (or ordinal... I forget) number of 
their submission... ha ha hA HA HAAA HAAAAAAAAAAA!

I'm okay with the current setup personally, as far as naming goes. I'd 
like there maybe to be a more formal classification, say CHS (CPAN 
Heirarchy Standard).  I like it, though, because it's fairly intuitive on 
my use lines.  We haven't had very many collisions thus far. And if they 
start, that will just force people to be more creative with their naming.

And about the local thing, if they don't use (no pun intended) the Local:: 
heirarchy for local things and their code collides and breaks, that's 
their problem.  Module naming can't be smart for us, we need to help out.
