yes but the input has to be through something other than the normal 
keyboard interface. You'll need an alternate input stream and you'll 
need code to watch that input stream. The most common, but becoming 
obsolete quickly, is a serial interface. Then you have your app watch 
the serial interface and handle the data it receives. Beyond my 
abilities, I think Sarah has done much more work in this area.
