Comment:

 (Not having looked at the current version of bridget: )

 1) From which host do we want to run it? From the same host as BridgeDB?
 Can we assume, initially, that we're not extremely bothered by the fact
 that a few bridges may be blocked because we probe them and they are
 within a censoring zone?

 2) Are we only testing ORPort reachability or are we aiming to test all
 PTs that a bridge's extra-info line lists? If we're doing the former then
 there isn't much to do for this ticket, the latter if more interesting.

 3) If we choose the latter option in (2) and if some ports are reachable
 and others are not, do we not list it as running or just remove the
 transports for which their ports are not reachable? The second option
 sounds much more reasonable.

 4) If we track which bridges we distribute, can we use geoip stats to help
 determine a bridge's blocked status *and* its reachability?
