Ah, wait, we could distinguish them. Just noticed that the gateway
feature uses a unicast 4 address header, while the multicast
feature uses a simple, 3 address unicast header.

That should work. But might look a bit hacky. And would disallow
using a 4 address header from the multicast feature in the future.
