Slightly off topic but, could you elaborate on the MirrorManager setup
for this? I've got a local mirror at home and would like to set up
automatic usage from my local hosts on my private NATed network. Did you
set up a single host netblock for your public ip address? I have cable
internet and my public ip stays the same for several months at a time
but it does change. Is there any way to have a more dynamic set up, like
a netblock on a domain name so I only have to change my DNS and
mirrormanager picks that up?

Thanks,
