Proactive steps to prevent DDOS?

Some folks may have noticed that I'm already listed on the NANOG 
program to give a talk on "pushback", a scheme for defending against 
DDoS attacks.  Ratul Mahajan, Vern Paxson, Sall Floyd, Scott Shenker, 
John Ioannidis, and I have nearly finished writing a paper describing 
the scheme; we hope to make it available on the Web within the next 
couple of weeks.

A note of caution:  this is a research paper; it's not something you 
can turn on on your router today.  I'm discussing it at NANOG because 
we really want input from operators and vendors on how feasible it 
seems, and on what we've missed.
