One thing you could use is "groupsock_tclsh": an extended version of the
Tcl shell that has multicast socket operations built-in. You can use this
to receive (& print out) SDP/SAP announcements using the following Tcl script:
set socket [groupsock_create 224.2.127.254 9875 127]
while {1} {
puts [groupsock_read $socket 8]
}
Of course, this script only *receives* SDP/SAP announcements. Creating and
sending your own announcements would take a bit more work :-)
"groupsock_tclsh" is available from
http://www.lvn.com/multikit/groupsock-download.html
