When Jon Postel agreed to my suggestion that Van Jacobson's SunOS IP
multicast encapsulation code should be released using protocol 4 (Van
had tested it with a temporary number), it was with the expectation
that applications other than IP multicast could use the same
demultiplexing eventually.  Right now the code discards any packets
that don't have a multicast destination address (for protection
against firewall hopping), but other policies could be implemented.
