See PEP 376, which addresses that issue.

Yes.

Where did you get that idea from?  Was there a particular part of the 
PEP I should change to avoid creating that idea, or did you have it 
before you read the new draft?

The same thing would happen now if you installed two distributions 
containing files for the same package.  So no, I don't think it's 
worth elaborating on.  The PEP is starting to get kind of long as it 
is; I'm already a little worried about backlash when this goes back 
to Python-Dev, actually, *despite* the fact that it's more precisely 
specified, simpler, etc. than the previous shorter version.   :-(
