Yes, but there are several companies about to produce lower-cost
optical and active copper cables for IB. Since "4 wire" ethernet is
pretty similar to IB, presumably they'll see a price drop, too.
We were showing several of these technologies working at SC last
November.
Also note that 4 gig FC is the same data rate as DDR IB.
Now what the final costs will be, who knows?
