This is a straight update to RFC 2205. It is minor (IMHO). Much of the content has been moved to a CCAMP companion draft draft-berger-ccamp-assoc-info-01

RSVP currently offers some support for resource sharing (historically designed with multicast applications in mind). However, this is restricted to sharing across reservations with the same destination transport address (ie with same Session). The proposed extensions retain the existing concept of resource sharing, but adds the flexibility to apply resource sharing across any arbitrary set of reservations. This has been known for some years to be a useful idea for call scenarios that are more complex that 1-1, e.g. 3-way calling, call-waiting, etc.

Supports telephony/video conferencing apps

The fact that most of the work is done in CCAMP should make this a small effort for TSVWG.

Yes, I can do this one (and I hope other directorate members might be able to).
