Perhaps this post is not the most appropriate; but for some time I have been
considering informing the experts here about the work done by the ATSC to
address the problem of multicast when no return path is available. See 
http://www.atsc.org/standards/a_92.pdf

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Audio/Video Transport Working Group of the
IETF.

	Title		: RTCP Extensions for Single-Source Multicast
Sessions 
			  with Unicase Feedback
	Author(s)	: J. Chesterfield, E. Schooler, J. Ott 
	Filename	: draft-ietf-avt-rtcpssm-03.txt
	Pages		: 37
	Date		: 2003-3-5
	
This document specifies a modification to the Real-time Transport 
Control Protocol (RTCP) to use unicast feedback. The proposed 
extension is useful for single source multicast sessions such as 
Source Specific Multicast (SSM) communication where the traditional 
model of many-to-many group communication is either not possible or 
not preferred. In addition, it can be applied to any group that 
might benefit from a sender controlled summarised reporting 
mechanism.

Internet-Drafts are also available by anonymous FTP. Login with the username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then

A list of Internet-Drafts directories can be found in

or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-ietf-avt-rtcpssm-03.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
