Slightly off-topic, but this intrigues me, more from a privacy perspective than anything else. :)  I was looking at the email thread you linked to and saw some confirmation this is happening (embedding unique identifiers in DNS queries), but I¿m still curious just who is doing this.  Are we talking Verizon and AT&T and the like?  And am I understanding how this works - basically the CPE provided to the customer presents it¿s inside IP as the DNS server via DHCP and then acts as a proxy for the NAT¿d devices?

I¿d love to hear more...
