Okay, after a LOT of digging (I've never coded sockets before, and my
knowledge of C++ is "Hello world" level at best), it seems we need to
patch the live555 library, specifically groupsock/GroupSockHelper.cpp
at/around line 214 (at the very least), with a statement similar to:

if (ethernetDevice > 0) {
   setsockopt(newSocket, SOL_SOCKET, SO_BINDTODEVICE, ethernetDevice);
}

And the option to optionally pass in an ethernet device in the various
constructors

Another alternative (Though I have no idea just how well this would
work) would be to put the call directly after the socket is built by
groupsock.
