I gave high RTT with high bandwidth a try:
server   --   delay  --  mbox  --  client
netserver   300/300ms  45/900mbit  flent

I had to run flent with "-s 0.61" in order to avoid errors with fping dying
prematurely.
Comparing noack, ack, and ack-aggressive, ack seems to give the highest
download rates.
Cake was setup with "rtt 600ms".
