We have included Scribe and are new working on P2PCast. P2PCast is similar to Splitstream (using multiple subtrees for parts of the data) but does not assume specific overlays. When nodes join/leave the P2PCast ALM tree some reorganisation of the tree may be required. This requires some messaging between tree nodes with P2PCast specific messages. The draft currently contains a message REFORM which could be used for this purpose, in which the P2PCast messages could be wrapped by the REFORM message. An alternative to using REFORM is to create a separate message which would contain the P2PCast messages. I would be interested in any views as to which option you'd prefer, either using REFORM or setting up a new message type.

Filename: draft-irtf-samrg-common-api Revision: 04 Title: A Common API for Transparent Hybrid Multicast Creation date: 2012-01-27 WG ID: Individual Submission Number of pages: 37 Abstract: Group communication services exist in a large variety of flavors, and technical implementations at different protocol layers. Multicast data distribution is most efficiently performed on the lowest available layer, but a heterogeneous deployment status of multicast technologies throughout the Internet requires an adaptive service binding at runtime. Today, it is difficult to write an application that runs everywhere and at the same time makes use of the most efficient multicast service available in the network. Facing robustness requirements, developers are frequently forced to use a stable, upper layer protocol provided by the application itself. This document describes a common multicast API that is suitable for transparent communication in underlay and overlay, and grants access to the different multicast flavors. It proposes an abstract naming by multicast URIs and discusses mapping mechanisms between different namespaces and distribution technologies. Additionally, it describes the application of this API for building gateways that interconnect current multicast domains throughout the Internet. The IETF Secretariat
