 Replying to [ticket:20132 teor]:
 > One of the things that concerns me about large tor client farms is that
 they download a ~1.5MB consensus per client per hour.

 It should in theory be compressed, so smaller than that. But yes, it is a
 lot over time, per client.

 > It would really help to have a client option for this in Tor, but there
 is a tradeoff - compromise that relay, and you own all the clients.

 In theory, this is what DirPort was for long ago. If you set up one Tor
 client with a DirPort, and set httpproxy on your other clients, then
 they'll ask their dir questions to the one central client. I guess this is
 a bit trickier nowadays with the begindir style questions, but that's a
 simple matter of turning off ... wait, it appears that we ripped out
 TunnelDirConns. Well, we used to have this functionality, back in the day.
