Yes, I'm wondering about the "almost always" case. Since machine1 has
multiple physical and vlan interfaces, shouldn't a (for example) server
bound to one of the existing physical interfaces be able to communicate
with machine2, provided that both machines know how to route packets to
each other over the vlan interface without IP address?
