The only solution that always works: Somehow create a dummy network. Connect the host to a hub that's otherwise not connected to anything, just to get its ethernet light to come on, assign some IP address. Or enable the wireless network in 'peer' mode, again not really connected to anything, but you now have an IP and thus broadcast address that channel access can use on that host.

I spent some time recently trying to figure out how to deal with this
with Linux (for my laptop).

The difference between libca and CAJ which I found is that CAJ won't
accept 'localhost' in the address list even when explicitly given.

For Linux I looked at the various virtual NICs including tun/tap and
veth.  I found that none of them handle broadcasts.

The only "solution" I found was to force my un-connected ethernet
interface to be active.
