being nmdm(4) an emulation tool, i'd say definitely yes, probably
even more useful if you provide a knob to enable/disable the speed
emulation -- i see a point in actually emulating the wire speed,
but also one in not doing so when the application is not speed-sensitive
and you just want it to run quickly.
