Hi Greg,

The following shows a pattern that's working well for me:

https://secure.simplistix.co.uk/svn/Simplistix/errorhandler/trunk

The "work" is in setup.py.

The development docs are here:

http://packages.python.org/errorhandler/development.html

Ignore the sphinx and buildout stuff if you're not using them, although 
I find both extremely valuable...

With the above, I'd do:

python setup.py sdist

...and then put the resulting sdist in a folder served by Apache.

To install on a given box, I'd then do:

easy_install --find-links=http://yourserver/your/folder yourpackage

Using setuptools for the setup.py means you can specify any other 
packages your need via the install_requires parameter .

I'd suggestion buildout or virtualenv for deploying to the servers too, 
installing into the system python's site-packages is yucky and means all 
projects on one box have to use the same versions of the same libraries...

cheers,

Chris
