Comment:

 As discussed in Wilmington, Shadow results look good. Will attach graphs
 after this comment.

 The shadow network used had 2000 relays, ~50k clients, and 5000 servers.
 Load was varied by adding/removing ~20k clients. Packet loss was varied
 from 0%, 1.5%, 3%.

 The TL;DR is the worse the network conditions, the better KIST does
 relative to vanilla Tor (AKA "AMAP" in the graphs).
