Ahh, I hadn't caught that. That's easy enough.

While this certainly sounds useful, it's a bit different from what  
I'm thinking of. I just want to gather up all of the original .egg  
files and put them into a tarball. Everything you'd need would be in  
there, and there could even be a trivial wrapper script that runs  
ez_setup.py with all of the right options to install those packages.  
This can give the user all of the easy_install options for  
installing, rather than being stuck manually dropping the untarred  
directory into the right place or adding it to their PYTHONPATH..
