To me this is the scary part: " The overall picture suggests that uTP has a serious flaw. If it simply relies on latency measurements to find preferred paths, it¹s likely to favor paths where it¹s successfully circumventing management. When a path is managed to give UDP priority over TCP (as is apparently the case in the Bell Canada network,) uTP will see that path as uncongested even as it's struggling to deliver TCP. In this case, uTP will in fact impair other applications, as we suggested in our previous piece."
" Another solution would be for traffic shapers to look inside the UDP payload in order to differentiate VoIP from uTP, but this approach is frustrated by the protocol obfuscation option that remains a live feature in BitTorrent over uTP. uTP will cause traffic shaping to become more expensive."
