I know of at least one nationwide DSL provider that ships (with
higher end products) a WiFi router with a single checkbox for "guest
network", which provides a captive portal style guest WiFi network
for folks who visit your house. The same box has had for years a
"DMZ" function for your gaming console/machine.
The guest network is a separate subnet. The DMZ today is not, it's
the wierd IPv4 pass-through thing many NAT boxes do to make weird
games work.
Still, it's all in a box thats given away for free by an ISP to a
new signup; and with IPv6 having more addresses I see no reason
each might not be its own subnet in 5-10 more years when IPv6 has
taken hold.
