Ah, ok. So I stand to my original statement (the one you classified
as incorrect): *If* I do misspell a package name, *then* setuptools
will correct the spelling if the index page is available.

And where somewhat slower could be "practically not noticable".

Sure: I don't mind at all if more people run your software on their
machines. If people want it more official, we can have
"cheeseshop0.python.org", "cheeseshop1.python.org", and so on,
or "de.cheeseshop.python.org", "jp.cheeseshop.python.org", and so
on.

As I said before: if people also want to mirror the files, I'd
ask them provide download statistics. Given the changelog, it
would be easy to keep a file mirror up-to-date (of course,
if a mirror downloads all files, these downloads also count
towards the download statistics - which might confuse people).
