On the subject of "we definitely do not want to tweak", I'd like
to remind you that during the early days of 2547 VPNs some of its
opponents were saying that they are against 2547 VPNs because they
do not want to "tweak" such a crucial protocol as BGP to carry VPNv4
routes.

Today AT&T has "2 million VPNv4 routes in the US alone" all carried
in BGP, and a successful 2547 VPN service. None of this would be
possible if we would not tweak BGP.
