The changes in this version clarify that position re "client" vs
"announcer/listener" (Dave Thaler); make all authentication schemes
optional (Peter Kirstein); and clarify when to send deletion messages
(Pieter Liefooghe). It does not address the issue of SAP vs SDP
authentication, that is left for discussion in the meeting.

The changes since the -04 revision are to remove references to client
in the text, now talks about SAP announcers and listeners only; clarify
that TTL scoping is discouraged in favour of admin scoping; clarify
section on session deletion; remove the optional timeout field from the
packet format; clarify why IPsec is not recommended for authentication;
and update references.
The timeout field was only used for encrypted SAP, in cases where a
proxy didn't have the decryption key. We now rely on either 1) the
receiver of an announcement understands the payload, and can derive
the session timeout from that (this is the common case); or 2) the
announcer sends explicit deletion packets when it stops sending the
announcement; or 3) the receiver will timeout an announcement which
hasn't been heard for some time (proxies which deal with encrypted SAP
can still recognize cases 2 and 3).

This draft proposes modifications and enhancements to SAP, the session
directory announcement protocol, for support of IPv6 conferencing
environments. Along with support for IPv6, a couple new features are
also introduced.
