I think what Steve wants to do is issue a REQ, send it to the PC, but
have the path record go to his embedded device (which has a different
LID).  The CM protocol supports this, but the implementation of the CM
looks at the path record to determine the destination of the CM MADs. 
Supporting this would require some way for the user to set the target
of the CM MADs independently of the path information contained in the
REQ.  Adding an optional extra path record for the CM path might do
the trick.
