Two major points:

1) Can we please have a proper implementation report for this spec?

2) The document does not define a mandatory to implement encapsulation
   method. All methods mentioned after MUST's in section 4 are conditional
   on statements like "when tunneling is done", and "systems that
   implement". In other words, interop is not guaranteed.

   I would imagine that the spec would want to mandate at least the
   MPLS/LDP one.

Note: -04 was Last Called in idr in February, satisfying our desires for BGP changes to be checked by idr.  The changes from -04 to -07 (other than the ones asked for in the idr last call) are minor and don't warrant another idr Last Call.

There probably shouldn't be a citation in the abstract.

The draft appears to recommend that a site use Unique Local addresses in preference to Global
Unicast addresses, through its quoting of the unique local draft's text here:

"They have the additional property that they will continue to work if the individual sites are 
renumbered or merged."

Personally, I believe this would be contrary to good practice if the site were not already using Unique
Local addresses, since it increases the administrative and routing burden.  I do not ask the authors
to share this view, but I do note that more direct recommendation one way or the other would be clearer.
