There is already has been some discussion about importing from command line:
http://mail.python.org/pipermail/python-dev/2003-December/041240.html

I suggested the following:

1. python -p package

     Equivalent to:

     import package

2. python -p package.zip

     Equivalent to:

     import sys
     sys.path.insert(0, "package.zip")
     import package
