I'm not sure if this is what the original poster was looking for.
My understanding is that he wanted to direct the standard output
of a command into two or more scripts that could run in parallel
using the tee(1) command.  I think this works:

% cat script0
#! /bin/bash
sed '20q' /usr/share/dict/words | tee >(./script1) | ./script2

% cat script1
#! /bin/bash
tr -d aeiou > script1.out

% cat script2
#! /bin/csh
tr -d tnshr > script2.out

% ./script0

% cat script1.out
A

It occurrs to me that if either script1 or script2 will be long
running that it might be expedient to run them in the background.
I'm not sophisticated enough with either sh(1) or bash(1) to know
how to do this, but maybe job control would suffice.
