Sorry, I misunderstood.

So you think the requirements are the same for residential users and
ISPs?  I'm having a failure of imagination, and can only imagine 
residential "TE" where a user gets a PA prefix from both her VOIP
provider and her gaming provider.  Maybe she wants failover with her
prefixes, but I don't see TE as I understand it.

If true, we need a BGP with more knobs than the current one, but
which is usable by Joe Homeuser.
