Why not?

Can you not just loop all the addresses you wish to restrict access to right back to 127.0.0.1?

I know, it is not intelligent blocking but used in conjuntion with monitoring software it is a good free alternative.

Has anyone here used the HOSTS file to such an effect?

been using it all the time so effective ;)

i think the old banner-free kazaa does it too.
