Quite interesting.
And now, reverse question : is it possible to create a raster from stdin ? I 
was having in mind to send the output of "r.stats -1", play with it, and send 
it back to...to...to this mysterious command that may not even exist, without 
having to write any file on the hard disk. Of course, you have guessed that I 
do not speak C.
Thanks for any idea.
