The "egg" is Python's binary distribution format. It's basically a zipped file with some extra metadata that you can give another Python user. He can "install" and use them. For details on what they are, please refer to http://peak.telecommunity.com/DevCenter/PythonEggs. Since it's a "native" format, Python can employ custom importers and the like.

I've been out of touch with the packaging world for a while now. There was some talk of discontinuing support for binary distribution formats. The relevant documents that I know of are at http://bitbucket.org/tarek/distutils2/src/tip/docs/design/wiki.rst
