It does use a list of mirros for the debian.  I haven't really looked
into it too deeply.
Furthermore the jigdo-lite program is really just a shell script -
should be easy to get it to behave however we want it (it just runs
wget).

I would really like to see dynamic DNS resolution based on source IP
giving out the address of the nearest centos compatible mirror - then
it would 'just work'.

And that's the problem... But we could possibly work with them to get
this working - at least for http this is relatively trivial (just
setup a virtual domain for whatever global name we would decide on
like mirror.centos.org).

There aren't that many files on a cd, so the extra time spent opening
closing connections shouldn't really be significant - unless you have
an extremely big pipe.  But - yes - we would want each user to use the
closest possible mirror.

No idea what this is... :-)
