Well, here's a quick-n-dirty proof of concept version of fastestmirror
with persistent cache of mirror response times:
http://laiskiainen.org/yum/plugins/fastestmirror/fastestmirror-persistent.py

Certainly makes a big difference, a no-op 'yum update' on my system is
around 11s when all mirrors are timed on each run, with the above
version the consecutive runs come down to ~5s.
