The directors are connected to each others in ring. Like you have
connections:

A -> B
B -> C
C -> A

So if B logs about "right", it means the B -> C connection. If it logs
about "left", it means the "A -> B" connection. The directors always
connect to their right side, so "out" should be always the same as
"right" and "in" should be "left". But until handshaking is done, it
simply logs in/out for incoming/outgoing connections. All of this could
probably be done in some other clearer way :)
