identd has it's limitations (rfc 1413, section 6 "Security Considerations")
but it can be usefull if you know what you are doing.
with an identd query in sendmail one can prevent forged mails
from joe average user (I know it's still possible - but it's better than
nothing) for example.

there are too many ports in ports/net - one reason we moved pidentd to
security.
libident and pidentd belong to ports/security - maybe we should add a
big warning about it's limitations...
