[p2p-hackers] SSM for Java?

[Nick Johnson]

Source-specific multicast (my original message was a typo) is an 
improvement on standard multicast using IGMPv3 that allows the 
receivers to specify the source IP of messages they want to receive. 
This prevents spoofing (to some extent, at least), and more importantly 
makes the job of routing multicast feeds much easier for the routers.
