Limited??? If you call the shuting down of mission critical networks
"limited" then yes your right. I think this is the major concern, I mean
so what if some pics get deleted, the users' workstation doesn't
(shouldn't) usually hold mission critical data (i'm talking about the
large sites here). The real problem is the network congestion caused as
a result of these "worms" sending themselves to hundreds of people at a
time.

I could be wrong here, but that's the way I interpret the situation.
