Hi,

In base draft, section 5.5.2.1 (about AppAttach), it states,

  "The application using connection set up with this request is
   responsible for providing sufficiently frequent keep traffic for NAT
   and Firewall keep alive and for deciding when to close the
   connection."

When such a connection is established by ICE, it means that it is
capable of multiplexing STUN bind and indication messages with other
messages (application). Wouldn't it be natural for the RELOAD layer that
completed the ICE check and DTLS to also use STUN indication message to
keep everything alive (firewall, connection, UDP session, etc.)? which
is identical to that of a connection created from the Attach message.

This is an inter-op issue that must be approved or disapproved by this
draft, so I would like to hear comments from the authors.

Thank you

--Michael
