ip_conntrack_identd?

[Myles Uyema]

Has anyone written a module such as this?  Seeing that identd is
generally queried only when I make an outgoing connection to another
host....

So only remote hosts that already have ESTABLISHED connections will be
able to connect to my identd port as a RELATED connection?

iptables -I INPUT -p tcp -m state --related --destination port 113

Right now, this rule is never matched, since I have no such module that
relates current established tcp connections.
