I don't know the DEMON algorithm.  But I would say you're on the 
right track.  If GRASS doesn't include the algorithm you want, you 
can include it!  Just a Simple Matter of Programming--you could do it 
in C, or C++, or even PERL.  Writing a new module for GRASS is not 
difficult.

I am a bit puzzled by your third question though.  If you've already 
decided to use DEMON, why are you asking how to use it?  Sorry if 
that's an obvious question; I'm a mathematician, not a hydrologist.
