Is the level of DNS cache poisoning and IP packet spoofing attacks in the 
wild similar?

Despite the fud about it, if there aren't serious DNS poisoning attacks 
will it still be considered critical?  Or will it just be one
more thing people don't care about? Heck, people are willing to 
point-click-change their DNS client settings to point to various 
untrustworthy name servers without needing to go through the trouble of
cache poisoning.

Of course, many hosts learn which DNS servers to use with insecure
DHCP.
