I can see this as an exponentional problem for packagers, but let's
think about it:
- How you would handle several version of the same package in Python then ?
- How each application would pick the right version ?
- How would you decide which version is the one by default ?
That is the core of the problem.
The -m feature of setuptools is nice, but it activates one version at
a time, and
this is globlal to Python unless each application is handling the
wich is pretty heavy.
A programmable sys.path ?
