I suppose you could have multiple mirrorbrain hosts with synced
config/database (pgsql streaming replication works quite well) and
then there could be multiple entries in the client's mirrorlist again.
Otherwise it could still be the same FQDN but as a DNS RR with
multiple records and a somewhat low TTL of 300s-ish?

The project sounds quite nice and well suited for the job and should
be able to centralize/unify or current situation, but I think we have
some other things with a higher priority than changing/optimizing
something that is working reasonably well currently.
