With how much identifying information user agents leak nowadays [1]
this is almost a moot point. If you can be uniquely identified through
the user agent- does it really matter that they can uniquely ID the
household as well based on prefix information?

All you need to do with what that site says is write a sh script that deletes and then creates the same user. Stick it in a crontab. Your browser ID changes each time. In addition to browser cookies, be sure to manage your flash cookies...

So, force the DHCP server to give you new addresses (in IPv4; don't know about IPv6, yet), manage your cookies, change your browser IDs regularly. What did I miss? ;-)
