There is s9.1 that addresses this :)

Since s4.2 of this document points to s4.2 of security-arch and there’s an entire subsection on ICE I am hoping that the references are enough.

I deleted the display requirements section because I think the prohibiting on negotiating NULL drives the display requirement.

Would something like this work:

  These are compared by the peers to authenticate one another.

I was really hoping a Dr. Evil included their info the DNS.  It wasn’t there.
I changed to http://example.org

Changed it to customerservice@xxxxxxxxxxx

I changed to “a poker site” to match that phrase, which is used in the 1st para of that section.

I have to admit that I’d probably be confused if there was a reference to SDP after "SDP-based like SIP [RFC4566]” and it reads a little awkward if we do "SDP-based [RFC4566[ like SIP.  RFC 4566 is referred to in s3 when the SDP attribute is defined and there’s a reference tor SIP, which also refers to SDP,  earlier.  I tend think the reader won’t be that confused ;)

The reference is a sentence later.

fixed

fixed (I just remove the [ ]).

fixed

Eh - when I read that I thought - generic requirements and then ones for media and the data channels.

I think I fixed this.

I’ll leave this for ekr.
