They probably don't -- but some appliance they buy might. Maybe some
home "family-oriented" box will put the kids' machines on a separate
VLAN, to permit rate-limiting, port- and destination-filtering, time-
of-day limits, etc. In the past, I had to do similar things -- no AIM
during homework hours, no file-sharing -- to the point that I had four
subnets in my house (wireless, teen-net, workVPN, and backbone/
parents). I don't expect the average consumer to set up something
like that, but I sure wouldn't be surprised at appliances that did.
