Another things to consider, since you're going to be doing so much
checking is to instead of just running a tor client, running an
authoritative directory server. If you don't want to deal with all the
traffic, you can just set it to only allow local connections and not
adversite. Another feature might be to run it through the peerguardian
lists ( and somehow "label" servers in
those lists.
