okay, but don't forget commodity pricing. "single IP address" is the market norm, it's what most users currently expect. anything different would be more expensive just because of the nuisance factor. that, and use of NAT is the current "conventional wisdom". this is changing, but it's taking awhile. also NATs are in some sense invisible. I don't know of any vendor that labels SOHO NAT boxes for what they are - they just claim that they are "connection sharing" boxes, or worse, "routers" - as if translating addresses were inherently a part of IP routing.
