Since auto-conf pretty much requires the LAN to be /64 sized and if you believe more than 1 subnet would be of use to the end-user/residence then there are only a few options left, eh? It seems that the ppp-o-e sorts of connections could pass out this information and make the lives of equipment/user easier, what sort of options were you envisioning? (or what were you hoping to avoid?) I ask because I'm fairly certain the operator and standards-body folks both would be curious about a vendor's (or vendor-ish-person's view) view on this issue, I just don't think a rational answer is forthcoming from the 'user' community on this quite yet :( -Chris
