    Technologically, what you say is possible.  You state that an entire sky
system would cost around $1100.  Your forgetting the $2000 to $3000+ cost
for the computer, one required for each camera in the system.  To be
effective one would also need several stations scattered across the country
or the world to collect this data.  In this day and age, getting money for a
"pure" research project is like extracting water from a rock.  At least it's
that way it is in Canada and I expect this is similar in the U.S.A.  If I
win a big lottery, I'll gladly fund a station! ;-)  I don't think the visual
observer has much to worry about, at least not in the near future.
