-      - Figure out how to actually modify bandwidths in the consensus. We
-        may need to change the consensus voting algorithm to decide what
-        bandwidth to advertise based on something other than median:
-        if 7 authorities provide bandwidths, and 2 are doing scanning,
-        then the 5 that aren't scanning will outvote any changes. Should
-        all 7 scan? Should only some vote? Extra points if it doesn't
-        change all the numbers every new consensus, so consensus diffing
-        is still practical.
