And conversely, just because they exists doesn't mean that any ISP will ship them - or ship them configured to anything more than a basic single network.

Besides, for this to work properly it's going to require VLANs and multiple wireless SSIDs unless you limit the network to the ports on the router. Good luck getting that to work with the average user.

I can see uses for about 3 or 4 segments - note, segments rather than subnets ! You are not clear whether you are talking about multiple segments or a single network with multiple subnets. If it's the latter then it adds almost zero security, if the former than it's beyond the average user to deal with.

Thanks - you've expressed it better than I would have.
