It's more a question of creating a new delivery platform, because the
currently used ftp mirrorring is useless for packages. The whole process
of synchronizing from upstream server introduces _days_ of delay into
the process, and there is no guarantee that you don't catch an upload in
progress, which renders whole mirror useless for a time period.

quick to fall out of style!
