my argument doesn't get that far, actually.  i think there will be no outages
because recipients of abuse won't feel that they can afford to toss out the
good with the bad in this particular case.  which is going to remind of me
tom lehrer's quip, "feels like a christian scientist with appendicitis" once
an EC2 customer instance gets infected with malware that then ddos's somebody.

i suppose i have been too prolific here of late, since i predicted exactly
that, but it's no doubt buried in some response of mine that you did not read.

i think it will be both, and more the latter than the former.  i'm basing this
prediction on leverage, risks, and costs.  if amazon and google and anyone
else who provides large scale virtualization (where "large scale" means there
is no in-person meeting to kick off the relationship, no credit check on the
customer, and so on) knows that their good customers are so valuable to the
rest of the world that some number of bad customers mixed in will not matter,
then their rational decision will be to discover the break point and enforce
that much and no more.  this is how big companies get big and stay big; it's
what ISP's have always done wrt their abuse desks; it's the break point i
sought to move with MAPS; and the basis for that break point is in a totally
different place for (server-side large-scale no-fixed-ip).
