Can iptables look at the content of a connection? The problem is that if 
a user is in a forum and another one tries to join him, they need to end 
up in the same image (at least right now). And we can't use different 
ports for this - we run through firewalls and NATs and all sorts of 
insane corporate IT setups so the choice of port is not completely ours.
