If you've got relatively recent hosts, you could use ipv6, and the
link-local fe80:: addresses.

If the two hosts are on the same wire, take a look at the interfaces
(ifconfig, or ip addr). There's a reasonable chance they've
self-allocated a ipv6 address that stats with fe80::  (its based on
the mac addr). You could then chat between the two hosts, if you've
got the fe80:: addresses, without needing to allocate addresses.
