That would be tricky, but perhaps possible using some extension of
connection tracking ... whoever makes a new connection to an ircd is
going to get the next ident query from that IP.

This is how I'd go about it. I've seen numerous identd's listed on
freshmeat which claim to be able to do this. It wouldn't be that
complicated, I think: look up the connection in ip_conntrack, query the
appropriate internal identd, give that reply to the external client.
