So Phil says that he runs a trustworthy IDENT server on his box. 
Fine.  But plenty of spammers, phishers, and other nefarious types 
out there will try to use IDENT as another vector to exploit for use 
in breaking into your system, or for tricking you into believing 
whatever lies they want you to believe.

Unfortunately, there isn't a trustworthy system to tell you which 
sites run trustworthy IDENT servers.  So, you've got to decide what 
the relative risks and values are.

Moreover, damn few sites run multiuser systems like that anymore. 
With NAT, you could hide hundreds or millions of machines behind a 
single IP address, and IDENT to the NAT/firewall box would be pretty 
meaningless.


Sorry.  IDENT was useful fifteen or twenty years ago, but there are 
far too many holes in that technique these days.
