If you had similar code running on two different machines, each of which attempted connections to the other machine, I would expect that they would never connect because of the asymetric nature of the TCP SYN, SYN/ACK, ACK connection sequence. Shouldn't the sockets API work the same regardless of whether addr.sin_addr.s_addr is the loopback address or not?
