Of course feeding 4 x 100MB cards into one hub would be dumb. I think the
MS test had 4 x 100MB cards feeding four independent groups of
workstations, which I think is pretty real world - at least its
compatible with my world.

Here in Hong Kong I have only seen one source of GB cards, at horrendous
prices, and hubs at far worse prices. Maybe things are different in the
US. I can get 24 port 100MB hubs for about US$250, and Tulip clones for
under US$20. In most servers, and server style motherboards, one or two
SCSI buses are included on the motherboard. With most boards now having
at least 6 PCI slots, 4 cheap Tulip cards in 4 of those slots sounds OK.

Anyway, if GB Ethernet is exploding in the U.S. maybe my comment was
inappropriate.
