I add your comment to the list of items which will be discussed during
the meeting. I will provide this list very soon on the mailing list.

There are cases of UDLs where a receiver can receive from several feeds.
Some satellites perform on board processing, i.e. feeds can transmit on
a different frequency toward the same satellite which 'multiplexes the
data' on the same downlink frequency. From the receiver point of view,
several feeds can transmit on the same UDL. For example, DVB
(http://www.dvb.org/dvb_framer.htm) standard allows this type of
transmission.
