Please incorporate the QoS issue brought up by Toby.  I'd like to make 
sure we have everything in the draft that the WG wants before issuing 
the WGLC.  I also think the TSV/RTG directorates/ADs will be interested 
in that.

Can you explain the rationale for the following the changes to 
requirement #5; I'm just not following it:

OLD:

5. One ADVPN peer MUST NOT be able to impersonate another ADVPN	peer.

NEW:

5. Any of the ADVPN Peers MUST NOT have a way to get the long term
authentication credentials for any other ADVPN Peers. The compromise of 
an Endpoint MUST NOT affect the security of communications between other 
ADVPN Peers. The compromise of a Gateway SHOULD NOT affect the security 
of the communications between ADVPN Peers not associated with that Gateway.

Is the first sentence still saying basically: "peers can't impersonate 
peers"?

Nits:

- sec 1.1: Need to add what an ADVPN is and expand the acronym

- sec 4/1.1: The terms allied and federated environment kind of come out 
of nowhere.  Please add them to s1.1.  I just to make sure it's clear 
what the difference is between the two.
