Finished off side, a little ditty that took an hour or two. It takes a filter arguement, and two file names. It then runs the two files through the filter (one at a time), and then displays the output of each beside each other. Therefore, the command:
./side "/home/mikal/opensource-stable/mi/i - < %s" ../shdns/sample-response ../shdns/shdns-response | lessTakes two DNS packets, and displays them after they have been pretty printed. The output looks like this:
/home/mikal/opensource-stable/mi/i - < ../shdns/sample-response | /home/mikal/opensource-stable/mi/i - < ../shdns/shdns-response

It handles line wrapping and stuff like that, but it is not a visual diff. It might one day be, who knows?
You can get the code from here.
