Comment:

 Does "bandwidth" mean consensus weight? Is so, I believe all-zero
 bandwidth networks are unstable because it's hard for a client to
 distinguish the network between different relays as no fraction of a
 relay's bandwidth can be made. Keep in mind that I'm not an expert on Tor
 design and this could be completely inaccurate.

 I think the solution is that if there's a bandwidth of 0, we automatically
 make it 1 either on the client or on the consensus. I haven't looked fully
 into a solution so this may be an imperfect one.
