=> Respectfully disagree. Many hosts already have L2TP, 
you're asking them to implement another protocol. 
If the operator doesn't have then he can have it, it's 
already available in products. An existing protocol that 
is already implemented is better than standardising 
a new protocol because it might be simpler to implement.

=> I'd like BGP tunnelling mechanisms to be independent 
of MPLS as much as possible. We can also do the same thing
for OSPF, IS-IS ...etc. IMHO these are the best auto tunnelling
mechanisms for the core.
