[ns] Actual information sent through packets

[Will Shaver <will@digitalfountain.com>]

     I'm trying to test a new multicast protocol, and part of that
protocol is dynamic in that the client does different things (that then
affect network traffic) depending on the packet information recieved. So
basically I need to place actual useful data into the ns packets.
I noticed that there is a A Protocol-Specific Packet Header section of
the help docs, and was wondering if anyone has used that, or has
developed a different way of sending actual information in the packets.
(Not much per packet -- like only a few bytes.) And what is the method
used for the client's picking them up and sorting them on the other
side? Any help would be greatly appriciated. Any code samples can be
sent directly to me if you don't want to spam the group too much. Thanks
