On thing that would eliminate many issues is to make the mirroring and repo 
building process transactional; I also know what kind of an infrastructure 
headache that would be to get and keep working.  

That is, as packages are queued for insertion into the main repo, all 
processes and regenerations are done, then the transaction is committed and 
the mirror stays consistent (ACID for the repo).  As it is now, there are 
windows (as you thoroughly covered in your message) where the repo and set of 
mirrors are inconsistent.

And, just like database replication (like Slony and others on PostgreSQL, or 
MySQL's replication engine), this is a tough problem to solve correctly.
