 Use multitee: http://code.dogmap.org/fdtools/multitee/

 Your processor could be, for instance, if you have execline installed:
 exec execlineb -c "
  piperw 6 7
  background { fdclose 7 fdmove 0 6 yourapplication }
  fdclose 6
  multitee 0-1,7
 "

 which copies stdin to stdout untouched, but also feeds a copy of
stdin to yourapplication's stdin.
