Point of clarification on Low Light Vision.  It doesn't let you see for a specific distance.  It makes any light source available twice as effective.<br/><br/>So, a torch that let's humans see clearly for 20 feet lets an elf see clearly for fourty.<br/><br/>But the point about mixed parties is pretty accurate.  For example, if there's kobolds up the tunnel watching us and cranking back their crossbows,  our light illuminates us to them, but not them to us.
