I'm wondering a bit what the shallow buffering depth means to higher-RTT 
connections. When I advocate bufferbloat solutions I usually get thrown in 
my face that shallow buffering means around-the-world TCP-connections will 
behave worse than with a lot of buffers (traditional truth being that you 
need to be able to buffer RTT*2).

It would be very interesting to see what an added 100ms 
(<http://stackoverflow.com/questions/614795/simulate-delayed-and-dropped-packets-on-linux>) 
and some packet loss/PDV would result in. If it still works well, at least 
it would mean that people concerned about this could go back to rest.

Also, would be interesting to see is Googles proposed QUIC interacts well 
with the bufferbloat solutions. I imagine it will since it in itself 
measures RTT and FQ_CODEL is all about controlling delay, so I imagine 
QUIC will see a quite constant view of the world through FQ_CODEL.
