I'm reading the groupSock source code these days.
I found DirectedNetInterface is a pure abstract class,
In groupSock::outputToAllMemberExcept(...), the member functions are
called, but I cannot find any implementation in the project.
I wonder what's this class used for?
I guess it can be extended and used for stream forwarding? or
application layer multicast?
Yes, we use this for our implementation of UMTP

Otherwise, this code ends up not being used.
