Hello again,

I'm trying to ASCII-fy so that I don't send another base64 blob.

I didn't have a look around your code. My whole post could be
summarized as: you're reinventing the apt-get paraphernalia.

I'd prefer to drop a python.list into /etc/apt/sources.list.d/ with:
deb http://eggs.python.org/apt <whatever> <whatever>
And use the rest of the tools I already have.

The really *big* -1 this has is that I'm basically gonna be using
--single-version-externally-managed eggs (which makes it impossible to
have multiple "inactive" versions and require() them, if I understood
Phillip Eby correctly).

I was thinking "sync local" re-gets the repository's Packages
master-list. Then you read in the locally installed ones (which is a
matter of traversing sys.path and looking for the .egg-info files; I
think those are now (as of 2.5) expected to be there.

All this has been done before; that's why I'm being so bone-headed about it.

I think easy_install -f <url> can work against an Apache directory
index. I thought that was the whole point behind it, really.
