It appears to be an unintended side-effect though.

It happened before. I have seen worms/viruses (like Nachia for example)
bring down WAN routers due to the overwhelming volume of ARP requests
from the scanning of infected machines. I've seen Bay routers swell up
and pop due to various tables being overflown. It happened before and it
will happen again.

heh... yeah, we've been blissfully playing the fiddle in our corner of
Rome which has been burning for quite a while now. Whenever the fire
invades our garden, we sprinkle some water and pixe dust on it and all
is well. Good thing we don't see all the flames in the background due to
the heavy smoke.
Ciscogate: Shame on Cisco. Double-Shame on ISS.
