Actually, if you use UNIX-domain sockets (AF_UNIX) then you do have
objects on disk....   errr, at least you do on an actual Unix machine (I
haven't used them on OS/400) you have a special file (probably in the IFS)
called a "socket".

With TCP/IP sockets, though, you're correct.

Not sure why you'd want to use AF_UNIX sockets, unless you're a Unix
programmer who just isn't familiar with the other methods :)
