Sounds like a good plot for a thriller novel! "Frederick Forsythe's Day of the Worm" :)
It *is* a good novel topic. The trick is to get it written and published before it becomes a documentary. :-)
Imagine the effect now of taking down the net for even one day. Something that didn't exist in a meaningful form even ten years ago is now something that if it was down for just one day would bring the economy of the world to a grinding halt. The cost would be imponderable.
