Sun Gigabit cards

	You need two gige cards and use the receive port from each (or as 
you say a monitor port that combines what it can on a switch). Argus is able
to listen on both ports at once. There is an interesting 3c905 driver on
Linux that channel bonds, which may be able to do the trick of combining
two input streams in to one as well (I don't know of a Gige implementation
though).
