Have their been any ISPs that have come forward to discuss their consumer IPv6 allocation plans? I don't think we should wrap ourselves around a model that says, "yeah, we need multiple /64s for consumers because that's the way a particular protocol works (SLAAC). Maybe we need another method. One /64 for a home network seems like overkill regarding address space utilization -- A /32 would be overkill. I know some folks think we have more address space than we'll ever use, but gee….
