Something along the lines of limiting the traffic the (broadcast critical) 
server has to deal with. Allowing everything on port 4000 through is fine, 
until a machine starts throwing stuff out to port 4000 at a high rate. 
Letting another machine ignore all the non-xml traffic reducs the load on the 
main machine. 

Of course this is the same company that runs windows servers for file sharing 
and a little program that sends signals down an rs232 wire to other equipment 
and lets 100+ people (most who don't have a clue) have the root password on 
linux based broadcast critical machines, allow telnet access into said 
machines, and log in as root straight away, because it's more "convienient" 
to use telnet and ssh is "paranoid".
