Related notes:

This issue has been discussed during the 19/08/2009 telecon [1]. Yves confirmed that a normal HTTP response (206) to a HTTP range request will do the job. The wiki page [2], which was incomplete, has been updated. More precisely, the content-range header in the response will have as value something in the line of:

Content-Range: seconds 11.85-21.16/3600

indicating thus the total duration of the parent resource. The UA will be able to display the complete timeline of the resource.
