A very good practical illustration: my colleague cannot "pip install 
mercurial" right now as the mercurial.selenic.com website is down for 
hours now.

All the download links on http://pypi.python.org/simple/Mercurial/
point at things like
http://mercurial.selenic.com/release/mercurial-1.5.tar.gz

I'm very happy to have a local buildout egg cache, otherwise the 
mercurial website's failure would bring a couple of my buildouts to a 
grinding halt.


A couple of those project that don't bother to put their packages on 
pypi can bring your pip or buildout *down* quite often.
