This is true, but if everything is on a switch, there'll be one host per
segment, and the only segments with traffic for multiple MACs will be
between switches.

If you've got a hub hanging off a switch port and a load of machines plugged
into that, sure the machines on that hub will see each other's traffic.

Randomly mixing switches and hubs on a network is not a good security plan.

I remember the first time that I saw Solaris x86 running. I asked why the
drive light was on solid. The person running the system shrugged and said he
had no idea, since no one was logged on and the system wasn't doing anything
at all.					- Russ Allbery in The Other Place
