  How would you get the UID of a Macintosh or PC-based client?  Or is your
proxy only going to service Unix clients?

  There isn't a reliable way to determine this information.  identd isn't
really a useful service, since the information provided is completely
voluntary, can be easily faked, and is hardly ubiquitous.

  Maybe if you describe what you're trying to accomplish someone might be
able to suggest alternatives...
