=> That words between brackets above are not relevant
to this tunnelling mechanism, this is more relevant
to a 6-to-4 relay model, which is not what is being 
discussed. Routing protocols can be secured. 


  Also, did you know that BGP tunneling has IPR claims?

=> No.

=> I think this depends greatly on who you talk to and
what their network looks like.

=> I agree that it's not specific to 3GPP, it is relevant
to any operator deploying an IP network so perhaps 
a general discussion on whether this is needed is better 
than associating it with any draft.
