My concern with that would be that an administrator may install Python, 
but the user may not have write access to that global location, leaving 
that user unable to customize the launcher.  OTOH, that is how things 
work on Unix today - such users could not change what /usr/bin/python 
points to).  Always using a per-user location would mean there is no 
opportunity to have global settings, but it is unclear which is the 
lesser of 2 evils.  Supporting both might even be reasonable if the 
rules are very straightforward.

I'd still very much like to see the change to the wording of the PEP to 
describe this feature though, otherwise I fear different people will 
have different assumptions about exactly what it does and how it does it...

Cheers,

Mark
