JFTR, this already exists. a.mirrors.pypi.python.org and 
b.mirrors.pypi.python.org are already there and could be used by clients.

My main worry (besides the client integration) is statistics: I do want 
to get download statistics. So anybody implementing it would have to 
find a way of fetching the download numbers from Amazon.

I also remain skeptical that this cloud idea is useful at all. Amazon
Cloudfront is a *beta* service. So they aren't sure themselves whether 
it works correctly - and there have been reports about two-day outages 
of EC2, for bitbucket.org. There also have been complaints about the 
available bandwidth. So I'm not sure whether replacing a single point of 
failure with a different one is actually improving anything.
