You're right about the firewall part. Also, unless you use an external
process to connect to the client, you'd run out of file descriptors; you
would basicly have 2 file-descriptors for each player, instead of 1.

Well, my suggestion is this (which is more-or-less what you proposed
yourself):
1. Setup a server socket on a port (either using socket-efuns or by
specifying an extra connection socket (ASCII or binary) in the
configuration file.
2. Setup callbacks (incoming, read, write) for the server socket.
3. The incoming callback (which, obviously, gets called when someone
connects) could/should check if there's any character(s) logged on which
has connected from the same IP as this connection. If there is,
associate the new socket with the player object.
4. The receive() apply should check if it has a pointer to the
client-control socket. If it has, it should send special binary (or
ASCII if that's your preference) to the client-control socket.
That's it! It hasn't been tried out, of course, but it should work.
There's probably a lot more elegant solution to this problem, but this
one was at the top of my head when writing this message.
PS. Has anyone running an LPMUD (i.e. MudOS, Amylaar, etc.) tried to use
a multiplexer for socket connections? This allows a very great number of
open sockets without increasing the kernel file descriptor limit.
