It's not very different from broadcast. I've copied code from an early prototype before I adopted ZRE. The prototype use address 225.25.25.25 (the foundation I work with is called z25 hence the 25). Portnr can remain the same. The socket setup is slightly different. We've discussed before setting the TTL to 1 so traffic is not leaked accidentally. Crossing multiple network segments would then be done consciously. I personally feel multicast should be the default. IPv6 doesn't even have broadcast and I haven't encountered issues with multicast on reasonable platforms. I don't know what policies are used in wireless networks but there's a chance that multicast is allowed where broadcast isn't.
