(I'm not trying to be difficult here - I'm just trying to figure out if we actually have any good understanding of this issue - and therefore any ability to predict what future worms might do to the Internet).
(Blaster was not bandwidth limited so that's a whole different animal - it seems to have been limited by a slow scanning rate, and a poor transmission probability).
