I like the idea very much. I though about it a week ago! :-)
You must know (and probably do about REM) the thing is, that the cycle 
with deep and shallow sleep takes about 1,5h. Optimal solution is to 
sleep during multiplies of 1,5h then you will wake up during shallow 
sleep and be more rested. My idea was to observe (by sounds and/or 
vision) sleeping person to guess when he/she fallen asleep. Then the 
1,5h counter begins.
Idea with ranges is awesome.
