Comment(by mo):

 I modified the description because the new objective is to apply a factor
 based on the country the relays are based in, so we need to aggregate not
 only by family, but also by country.

 We should play with deriving a factor that is inversely proportional to
 the total exit probability of the country, and combine that with a
 constant per country which can be tweaked in respect to laws (treaties
 etc).

 quick draft pseudo code
 {{{
 for all relays:
  exitbw[relay.family][relay.country] += relay.exitbw

 for family in [0..families]:
  for country in [0..countries]:
   cashout[family] += exitbw[family][country]
                      * constantfactor[country]
                      / exitprobability[country]   # take care of 0
 }}}
