Right, I understand that the sky is the limit when you can do bare-
metal programming on the Uthernet side.  However, under the control of
a mammoth OS like OSX, Windows or Linux, what sort of constraints is
one likely to run in to?  I remember that the Nintendo DS implemented
some sort of proprietary MAC-based communication method, but in order
to talk to the DS from a PC you had to have a specific wireless card
and replace the driver, etc.  Is it possible to do bare-metal
programming like this without having to go as far as writing drivers
in a PC world?
