Nothing, but nothing stops them from writing a bittorrent client which does "optimistic ACK" either. Yet noone seems to bother. Also, bittorrent marked as EF could easily get hit by a "don't queue voice packets, just drop instead" policy. Late voice packets are useless and might as well be dropped, but TCP streams like bittorrent react badly to packet loss. All in all there is little incentive for people to game the system. Should it happen anyway, network administrators have plentiful tools for fixing it, up to and including ip link set dev whatever down. /Benny -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
