I think that ssh expects the socket to already exist, with something 
listening on it to accept the connection. It won't create it itself.

Demo:

(in window 1)

% nc -lU /tmp/testing

(in window 2)

% ssh -R 1234:/tmp/testing cloud2

(in window 3)

% telnet cloud2.example.com 1234
hello

(in window 1) I see "hello" appear.
