As it s today, site-packages is just the default place, that is added and scan
when Python starts. And you need root privileges to install packages there.
There's another place where you can use when you are not root:
per-user site packages.
But those two place are just the places for "python-the-package-manager".

PEP 376 comes with a set of tools that will allow you to
in an arbitrary site-packages folder, and play with them. So it
basically makes almost no
differences for tools like zc.buildout-the-package-manager that is
tweaking sys.path in
the generated scripts.
I guess the simplest way will be to make the "eggs" directory a
like folder. It will even simplify the scripts because you will not
have to add one entry per eggs
there as it is today.
What could be awesome is to see a branch of zc.buildout built against
when it starts to be usable, to experiment this.
zc.buildout is a package manager, so it makes it one of the target use
case for PEP 376
and other changes we will provide in distribute.
