There are many points :]. The two below are key challenges.
I *know* I've sent ~3 or 4 email with the list of reasons to the list. I
just can't find them in the archives. Anyway, if the 'two points' are
addressed, then I can see if any other challenges arise...

False assumption. That's not a precondition for setup.exe, not since
federated setup.ini support was introduced. (= multiple mirror support).

Hmm, it's an interesting approach. I'm not sure it's needed though, as
the metadata about each mirror is already present, so any cache
cleansing can occur with smarts, and that's the only use that comes to
mind for partitioning.

It's no better or worse than an encoded mirror in the tree. All our
filenames are short, things should be fine.

Yes, but I wasn't referring to code quality, rather design quality.
