  The Gen-ART Review by Ben Campbell on 15-Mar-2011 includes a
  an issue.  I'd like to see this resolved, but I am not blocking
  the document from approval.

  run over UDP. After reading the updated draft and the related email
  thread, along with the change to the SRV record discussion to remove

  However, it seems that any IP-based transport protocol could be used.
  Is correct?  If not, please include an explanation.

In Section 3 we find:

   BTMM uses "_udp" to tunnel packets between the
   two ends to achieve NAT traversal.

I think you mean "UDP", not "_udp".

   My Mac Encryption Certificate".
