Re: [RFC] Campaign »Buy/Sponsor a relay.«

While I understand your concern I disagree since we're already in this boat.
I'm currently running a relay with Comcast as my ISP, and if I was going to
run an exit I'd go back to the past list correspondence about low-hassle
(tor friendly) hosting solutions. In both cases my ISP or hosting provider
are seeing the traffic of hundreds of tor relays. They're the points of
potential mass data aggregation we should be concerned about for this sort
of large scale eavesdropping, not necessarily the relay's operators.

Hence, as long as any hosting entity properly set the 'Family' parameter, I
think we should welcome this sort of hired-relay-operation. The proper
countermeasure for this problem (imho) would be to grant relays an implied
family based on geoip data and known ISP/hoster ip ranges (ie, don't make my
circuit through multiple relays hosted by Comcast or, say, in the US).

Just my two cents... cheers! -Damian
