COMMENT:
----------------------------------------------------------------------

I find myself rather unsatisfied by 

   The SPRING architecture SHOULD leverage the existing MPLS dataplane
   without any modification and leverage IPv6 dataplane with a new IPv6
   Routing Header Type (IPv6 Routing Header is defined in [RFC2460]).

in that the prospects for use of a new routing header, and ipv6
router/extension header treatment  seem poor. and the potential
consequences for chaining these for example seem worth exploring before
electing that course of action.
