The Darwin/Mac OS X scheme only deals with IOKit because that's where 
the drivers live.  The protocol implementation is in the directory 
'xnu/osfmk/kdp'.  It's in essence a UDP protocol, and is implemented 
without using any of the system's networking scheme (except for mbufs).  
The implementation is polling.  The implementation is pretty 
light-weight.

Justin
