Well, you can pass fds between unrelated processes (via unix domain
sockets and sendmsg and general uglyness), but this scheme doesn't need it
because..

.. the children just inherit the socket when they are started.
Maybe I wasn't clear, the approach I was suggesting has the central
game server as the parent of many fork()ed children that actually talk to
the clients. The socket is set up once, in the parent process, and
inherited by all the children.

That's what I was describing. Once you have that scheme in place, you can
potentially move code to do things like batching up client input into
lines, output compression, etc. into the children - these are pretty much
independant of the game itself, and seem like a relatively easy way to
take advantage of whatever hardware parallelism you have available.
