SDR

SDR prints session announcements from the MBone. SDR will only work if you have MBone/IP Multicast. It's a good test to see if you're on the MBone - if it prints stuff, you are, if it doesn't, you aren't.

Programming wise, it demonstrates how to create a mcast_socket for receiving. It would be neat if someone wrote a good SDR program - the only ok one I know of is written in TCL (and I wrote one in Java, but it's barely ok, though usable - see the JSD homepage). No, wait, don't - Jungle Monkey could easily be improved to do everything SDR does.
