It buckets data and puts it into redis. Really “dumb” but it works well enough until better infrastructure can be put into place.

"pip install thatproject" (and equivalent commands for other tools) looks the same to PyPI regardless of whether it's a human or a script running the command.

Yea this part is hard/impossible :/

Nice analytics for package owners is on the road map, but it’s, as you mentioned, down the road map a ways.

There's a demo instance (using live data) running at preview-pypi.python.org, but that's mostly focused on backwards compatibility testing for the tool APIs at this point rather than being navigable through a web browser.
