Yes, this has been done in Germany for {de,de2}.archive.ubuntu.com for 
instance.

Yup, this might be a workable idea, you'd need to start off by collecting 
reverse mappings (or registry handles for IP ranges) and associate them 
with the mirrors.

That said, I have some reservations about the ammount of work involved in 
setting up and maintaining all these tables. But then again, even at 
worst choice of mirror, it wouldn't be worse than the current choice, 
really.
