Some spam, although not much, still originates in the US. Forged headers and spoofed IPs increases the difficulty of tracking it down. I don't think any LAWS currently address this. True, it wouldn't do anything against foreign spam.

Most people who install firewalls and NAT routers do so without the intention of commiting fraud. Those who do allow their friends and neighbors to freeload would run afoul of their provider's TOS, but these bills would also make that a criminal offense.

DDoS networks, which are usually intended to hide the controller's address, would also be outlawed. And that's a good thing.

Anti-spyware and personal firewalls do not attempt to conceal or circumvent anything; they're intended to block communications which could be harmful to the user's equipment. Even a NAT router, which might "hide" the fact that you're using five computers on your broadband connection, is not concealing "the existence or place of origin or destination of any communication", as your public IP address is still on every packet you transmit. There is a method for counting the number of computers behind a NAT router, if an ISP really wants to be that petty.

But, IMHO, this would not make firewalls illegal. Everybody uses them, and I wouldn't think these states would really want to shut down the Internet by being so stupid.

As it happens, I use AdAware to block popup ads and ad banners. If you choose, you can also use it to change your apparent IP address. I tried it out (out of curiosity) and found that spoofing the IP address seems to slow the browser and make it unstable. In any case, my chief interest in using a firewall is to block hackers from accessing my computer. I don't mind if web sites see my IP address, as long as they don't use it to put spyware into my computer.
