No no, wait, the text is very clear about the use of TCP/IP, hence of
communication over a network (AF_UNIX socket can be used only for IPC on the
same machine). The phrase "UNIX STREAM sockets" is to be interpreted as
specifying the use of sockets as implemented by BSD UNIX and descendent, of
the stream variety (SOCK_STREAM), and with TCP/IP for transport/network
protos. This as opposed to other implementations of the same idea on different
OSs (e.g. the WinSock standard for comunication over proxy servers, mainly
used under MS-DOG/Windoze).
