A switch which is totally ignorant of VLAN will simply pass all traffic to
all ports (modulo mac learning).  This is distinguished from a VLAN aware
switch that has it turned off (common for netgear equipment), which might

For many homes, the 3800 may be the only physical switch... a homenet router
discovery protocol would also notice if 3800s were directly attached...
The layer-2 VLAN idea fails if we have a routed homenet and there are a
variety of devices invoved.  That's why, I think that GRE over IP would win
for most homes, and yet keep the wired multicast and wireless multicast
