I'm not sure what's the point of trying to rule out perfectly-valid 
deployment scenarios with statistics that are, for the most part, made 
up, and that are simply that: statistics -- that doesn't rule out a case 
where a router is connected to a switch.

If one doesn't want to support that common case, then I guess that 
should be said up front in IPv6 specs or deployment documents. Of 
course, one would never rule out such common deployment scenario.

Ironically, most of the folks participating on this mailing list employ 
such set up at home.

Thanks,
