The problem with this is that any time a cvsup server operator
decides to renumber their mirror, they need to inform the soa
for freebsd.org (and factor in the freebsd.org TTLs to manage
the change).

In practice this will not work, and will cause 1/n cvsup attempts
to fail after a machine has been renumbered until TTLs expire.
