An interesting idea. In my case, I average about 3 calls per month to Comcas=
t. I suspect this more than consumes the $99/month I pay them for internet s=
ervice. Further, I often get service credits out of those calls that further=
reduce their income.
If they provided native dual-stack with BGP and their service didn't go down=
on a regular basis, it would result in fewer calls, at least from me.

I don't want the residential customers themselves running BGP at all. Howeve=
r, if there were motivation on the provider side, automated BGP configuratio=
n could enable consumers to attach to multiple providers and actually reduce=
support calls significantly.
