To me... it sounds like a good idea... but needs a little refining.

Let me clarify the three type of packages in any python system:

 1) Project Packages (needed by projects - ie subdirectories/eggs)

 2) User Packages ( introduced python 2.6 windows version)

 3) Site-Packages ( /lib/site-packages)

Anything else.... is really lost or just misplaced.

If we think of all packages in these three divisions, it will give
us more clarity in providing what users are inevitably after.

There's no need for this... given that all the mechanisms for tracking
packages already exist. But only knights of the old code know where
it all is and how it works....
