Summary: Ready

Major issues: None

Minor issues: None

Nits/editorial comments: 
 - 3 pages 3-4: there is nothing about multicast which is an option
  for relay - agent exchanges. As multicast IPsec is a bit hard I
  understand this choice...

 - 3 page 4: there is a MUST for transport mode: I agree transport
  mode is better for this use but I am afraid not everybody in the
  security community will share this opinion. I propose to keep this
 and to wait for the security directorate review.

 - 4 page 4: I suggest: multiple relays -> relay chains

 - 4 page 5: I support your considerations: this use case is at least
  known plain text.

 - 4 page 5: preshared -> pre-shared
