Nothing would ``search'' a mirror; the classifiers merely ask the
servers for their list of IDs and then check whether they know about
those articles yet. For articles they don't know about, the classifier
will retrieve the article and do whatever magic it does to articles
(i.e. pass them to moderators, or just automatically include it in a
text-searching index or whatever).

There should be a master server list (perhaps each mirror could keep a
list of all the mirrors it knows about; thus the server list would be
mirrored). Classifiers would have to worry about accessing ``all''
servers if they want.

Potentially, a ``master'' list of article IDs could also exist...

Users would still access the system through the front-end of a
particular classifier. They will not know -- and should not even see
-- the existence of multiple, distributed back-end servers.
