Actually they're all documented in kernel(3) (where one might expect
them to be:-).

The documentation happens to be correct for epmd too:-) - there is no
way to tell it to bind to a specific address. Given the existence of
inet_dist_use_interface for the VM itself, it would make sense that epmd
had something equivalent (not necessarily calling an IP address an
"interface" though:-) - maybe contribute a patch?
