*DON'T EVEN THINK ABOUT THIS!*  The ability to arbitrarily redirect
input and output among devices/files/pipes/networks is what makes
the unix toolbox approach work.  Take that away and you would have
a fairly useless operating system.  Imagine wc working only with
typed input - how often would you use it?  A reasonable approach would
be to make the local machine (terminal/PC or whatever) handle more
operations locally and generate a standardized output stream.  Personally,
I don't care to waste any CPU time watching for meaningless transitions
of the <shift> key.
