Firewalls won't work…
Good notes from Ray Ozzie about the problem with firewalls. Folks in homes and in business are going to discover this soon.

The Internet is like a dirty stream where you want to get a little clean water. Even one little leak pollutes everything. This means that the vulnerability assessment and individual PC monitoring tools had better get much better.
Just think what would happen if a student went to school, picked up a worm and them wifi’ed into a home or into Starbucks. Everyone would get contaminated. At “Ignition”:http://ignitionpartners.com, even on our private IP addresses, we get 20 pings per minute from various hackers trying to get in.
