Of course.

And you don't have to be bothered by IP routing at all.

They can.

Just as RSVP is a copy of Q.2931, IntServ specs are copy of ATM
service classes. :-)

Unlike NHRP, it is a self-consistent approach having it's own
applicability.

I hope you can pursue that side of goal somewhere without
being disturbed by an architectural principle of the Internet
as described in RFC 1958 that, at the internetwork layer, IETF
concentrates on IP.
