There's already such an option; --find-links or -f lets you specify 
URLs that should be checked before *any* PyPI access occurs.  If all 
dependencies can be met using those URLs without going to PyPI, and 
you haven't explicitly requested -U (--update), easy_install doesn't 
go to PyPI.

You can also specify such links in a setup script using 
setup(dependency_links=[...]), which bakes them into the .egg.  When 
searching for that egg's dependencies, easy_install will pick them up 
and use them.

So, it's actually possible to install a package and all its 
dependencies without using PyPI at all, if the package author(s) bake 
the URLs in.
