I guess the hypothetical would be if you were in charge of security for an AS what would be the cost to put a best-effort worm mitigation system in.  The second question being how would you scale that cost with the size of the AS.  Maybe it is a case that there is not a best practice to fix a cost to, too much variability in the market and theories of how best to defend, if defend at all.  Just figured it would be prudent to ask before we made something up - usually not such a good idea.
