It is because there are 5+ billion people watching every single letter
you write to this newsgroup - you just get a little nervous ;-) But
you'll get used to it...

Hmmm. I don't really know the answer to that. Common sense would be yes to
that, since each point in the array ought to look toward the point_at
instead of a central point source... except you know how area_light behaves
for specular hilights, right? Single point. So it could be that it becomes
singular in the same way.
Only shadows are treated to the multiplicity of the arrays, which makes it
all about shadows. Maybe it actually skews along lines between array
rectangle and point_at vector. Or could be that it makes the array behave as
though 'orient' were used.
Something to check into. Now you've got me rethinking, even moreso, what I
thought I already knew. Like so many others, I typically go about finding
out about such things by experimentation. I.e. scene creation first, then
discovery of the results. I'm not always working from the documentation.
