There's an ident daemon out there which allows the response to be
hardcoded to a specific user / value iirc. Or I'm sure someone could
hack something up in perl / python / winner of the scripting language
holy war this week to do the same.
For years I've rejected outright ident connections and flipped the
appropriate bits in exim not to request it but I know there are plenty
of daemons out there (not just smtp) which look for ident information on
a connect.
