You may be right about the full-duplex Greg but he can still take some 
of the networking load off of the CPU by using a card that is faster 
than the SBUS speed.

Since the card is faster than the SBUS on the output it is idle a fair 
amount of the time.  It can pass the networking data off the bus faster 
and thus free the bus up quicker than the existing 10mb circuits.  Thus 
the SBUS isn't tied up with extra cycles waiting for the data to go out. 
  Thus less overall system load where networking is concerned.

But then wouldn't full-duplex make the 100mb even that much faster? ;-)
