If you're particularly concerned about giving away userids there are
various ident demons that will send something other than the login name
(such as a securely encoded form of the login name, or even some random
string that contains no useful information).

The point is more to provide a cookie that the remote site can give to
you when tracking down some problem than it is to provide information 
they can use directly - if you trust your identd, it saves you a lot of 
grovelling through logs.  It may even be the only way you have of 
identifying the user responsible on a multi-user box.
