In my case, someone found my package on a web site and wants to use it.
She's not a developer, but simply wants to click and install. My
thinking is that an egg describes my package and all of its
dependencies. If clicking on the egg ran easy_install, the dependencies
would get resolved and missing packages would be installed.

But then I need to bundle all the dependencies. What if some were
already installed? What if I'm inadvertently downgrading packages
because I missed a release?

yum (or equivalent) would handle the download and installation of the
dependencies specified in the rpm. I would not need to bundle
additional packages in my rpm.

We are probably in agreement about preferring the native packaging. For
Linux folks, I'd provide an rpm and expect their packaging system (yum,
apt-get, or whatever) to resolve everything. Is there any kind of
Windows package manager that would resolve msi dependencies?
eggs provide a cross-platform distribution mechanism for Python code.
Bypassing the platform package manager is an unfortunate side effect of
People can convert an egg to their preferred package format.
