Well, let's talk about "worst-case ddos". Let's say, 50mpps (I have not heard of ddos larger that that number). Let's say, you can sink/filter 100kpps on each box (not unreasonable on higher-end box with nsd). That means, you should be able to filter this attack with ~500 servers, appropriately place. Say, because you don't know where the attack will come in, you need 4 times more the estimated number of servers, that's 2000 servers. That's not entirely unreasonable number for a large enough company.
Botnets were the topic at today's Info Security conference in New York City. <http://www.infosecurityevent.com> Coincidences? Or just as random as your iPod shuffle? Jose Nazario estimated that there were 10,352 botnets active on the Internet earlier this year. You will probably always be outnumbered on the public Internet.
