Hi, i'm happy other people thinks it's useful. Thomas said it could
implement it *eventually*, IF there is enough interest.
@Marc Dion, actually it's geared more towards another use case, mostly flat
mesh lights out of camera frustum to light subjects, withtout the need to
touch anymore its strength and instead focus on size/position etc to get
desired result...

Hope to hear from other Cycles module member Greg and Matthew too. It's one
of those optional little features which improve daily work a lot.
