I don't think that it's a good idea. Since epmd works silently it's easy
to create a mess if you'll start another Erlang application in distributed
mode (after ejabberd it'll be unusable, before ejabberd you'll get the
same binding to all interfaces but will not be aware of it). The less
options epmd supports the better.

I think that it's better to simply protect port 4369 by a firewall rule.

Cheers!
