Yeah, SMB is so blame chatty, and so impatient, that it just cacks
on a hub. I'd never have believed it before, but when they can
get a 24-port 10/100 DLink switch for $91 from newegg (shipped!), why
mess around with technician time? At typical consultant bill rates,
that switch will cost them less than an hour of technician time.
I bet if you fire up ethereal on that hub, you'll see plenty of TCP
