Thanks. I've replied to your comments.

I think the current PyPI mirror can be highly simplified once we introduce 
end-to-end authenticity with GPG. My suggestion would be to make them simple 
file servers, or even drop them and switch to commercial CDN, that would 
simplify lots of management. What we should drop is the concept of a full 
mirror, as it creates lots of security headaches as you say. I think the PSF 
board is open to a proposal to set up a budget for this.

I think TUF is a large superset of what I proposed, that means that it is also 
a large superset of what it is (likely) needed. I'm still worried of how we can 
simplify TUF from an UX and IT perspective. I think that I need some inputs 
from you. Can you please write down something that describes:

1) What is exactly expected from a package maintainer to do to:
 1a) register themselves as package maintainers on PyPI
 1b) sign/publish a new package
 1c) hide/show a package version
2) What modifications are required on the PyPI server? How many GPG keys the 
server would need to handle? Would they be online or offline? What processes do 
we need to setup?

I would expect such document to describe also required changes to distutils and 
PyPI protocols, if required.

There is no specific hurry, though I would like these issues to be sorted out. 
I'm happy to integrate TUF if it's the best solution, but we need to discuss 
how.
