Unsynchronized simultaneous reads are not a problem.

Regarding the example you gave, though, it could be accomplished in a single pass by a single process (sed or awk, to name a couple tools).

emp_hub

emp_hub(6)							   Games Manual 							emp_hub(6)

NAME

       emp_hub - Empire multiplexer

SYNOPSIS

       emp_hub [-persistent] [-debug] [-help] [-mirror] host port localport

DESCRIPTION

       emp_hub	allows	multiple  clients  to  simultaneously  connect to a single Empire country.  This allows you to use both a fast and a smart
       client simultaneously.  It also permits multiple corulers to log in at once.

   Parameters
       host	   Hostname of the upstream server.

       port	   TCP/IP port number the empire server is running on.

       localport   TCP/IP port number the emp_hub should listen to for incoming client connections.

       -mirror	   Copy commands and replies to all clients using new protocols.  Currently only the lafe client  is  aware  of  these	protocols,
		   though most clients will ignore them.

       -persistent Normally  emp_hub  exits  after  the  last  client  disconnects.  With this option emp_hub does not exit, and will wait for new
		   clients to connect.	emp_hub must be killed by the user using the kill command.

       -help	   Brief usage information.

       -debug	   Print lots of messages, including everything sent and received by a client.	Useful when debugging either emp_hub ,	a  client,
		   or the server.

SEE ALSO

       emp_server(6), emp_client(6), emp_hub(6), pei(6), eif(6), http://www.empire.net/~harmless/guide.html, http://empire.idlpaper.com/

BUGS

       Due  to	the  nature  of  the empire protocol, only one client may have input focus at one time.  If a client pauses at a context sensitive
       prompt from the server, all other clients will be unable to send data.
