Umm...run a "secure" ident server instead of forwarding to another box?
AFAIK ident is a relatively simple protocol, and bullet-proof versions
should be available...perhaps even customizable for your purposes (I'm
sure someone else could benefit from an Exchange/ident faker).

   For the Japanese, by contrast, the human child is
   born in a state of loneliness, incapable of communication
   with the rest of humanity.  The way out of this
   loneliness leads by way of tenderness into a proper
   sense of dependence on others.
