Do we see udp port 53 hijacking as the next step in this ?  I'm curious as 
to what is the driving factor for doing this was.  Cash from advertisements, 
lower cost of support resources, phishing protection?  Lots of software 
depends on getting a correct DNS response, even if it's NXDOMAIN.

As I mentioned above, how long until Charter's OpenDNS users are forced back 
to the local cache based on port 53 queries.
