Hi Ron,

How about all of the above minus need for new routing header and zero
overhead (except one IPv6 encapsulation) with far better scaling properties
and no dependency on number of transit hops ?

Hint: Reference based Routing RbR

Do you think that if someone ships RbR there would be even single advantage
to use CRH ?

Thank you,
R.
