As a followup then, I just sent 50 standard DNS query packets and 50
DNSCurve encrypted packets (streamlined format, even) from my laptop
on my home network to the x.dempsky.org name server.  All 100 packets
arrived from the same source IP address as I see at
http://whatismyip.com, and I received all 100 responses correctly.

Either Comcast has broken my DNSCurve public key or they're not
tampering with DNS traffic. :)
