Hi Adrian,
Are you referring 6PE (http://tools.ietf.org/html/rfc4798) or
something new?
Not MPLS, no. Its IPv6 over IPv4 (protocol 41) tunnels and how to link IPv6
islands in a more seamless way using BGP.
If this is the right place to raise the issue I'll provide a few more details
of the issues and solution if you like.
Maybe you should take a look at the softwire WG. They're dealing with
similar problems.
But I fear there so far the idea hasn't gotten much traction. In fact,
the RFC4798 predecessor documents [1] included ability to set up
tunnels over GRE and similar non-MPLS encapsulations. This was
explicitly _removed_ because the solution was targeted at MPLS
networks, not as a general purpose BGP-signalled tunneling mechanism.
[1] take a look at e.g:
