I wondered about tee too, but couldn't see quite how it would do it.
(Does not help that 'man tee' just gives a brief useage then refers
you to an info page...)
mkfifo PIPE1
mkfifo PIPE2
# read a keybrd line, echo it onto both pipes
while true ; do read xx; echo $xx > PIPE1; echo $xx > PIPE2; echo next:; done &

elsewhere
tail -f PIPE1

elsewhere
tail -f PIPE2
