Its been my experience that the 4D/20 runs dog at about 12 frames 
per second, while a 4D/70 runs around 20-25 fps.  This results in a 
significant advantage for the pilot on the '70.  The same is true of
the GT, since it runs a different version of dog that has different
models for the planes.  It does about 15 fps.  All of these figures
are fundamentally unrelated to ethernet performance, but have more to
do with fill rates.

Dog compensates by adjusting the flight characteristics according to
the frame rate.  This keeps the '70 from (literally) flying circles
around the PI pilot, but doesn't address the problem that one pilot
gets twice as many frames in which to react, shoot, etc... as the other.
If anyone has a suggestion for this (other than fixing the frame rate
so that it runs at exactly the same speed on all workstations), let
me know.
