I do think it might just work well enough if the accelerometers provide 
sufficient data. Additionally it could be adapted to you personal habbits. 
The movement you make when you take the phone away from your ear to hangup is 
probably pretty much the same every time, sufficiently smart software could 
learn to recognize it. 
But it should definately provide a fallback unlock (aux button, screen 
gesture, whatever) and it probably should be biased towards locking, at least 
during a phone call to prevent you from accidentally hanging up.
