It's just going to get very difficult very quickly to manage such a meta
egg with over 100 or so dependencies. Though I guess there'll be
automated tools to manage this.

I think another alternative is to separate the releases into different
"repositories", kinda like "All zope 3.0.0 eggs are at
http://download.zope.org/distribution/3.0.0/".
