I think your stated workflow is fine until someone is lazy or makes a 
mistake and does not bother to check against reference behavior.  It is 
useful to make people explicitly think about changing the regression 
traces, IMO.

But, if you are suggesting that there would be default stored test 
output that is not largely trace-based, used for regression testing, and 
that you want to be able to turn on even more pcap/ascii tracing for 
even more checking, then I agree.

For trace diffs, I typically just "tcpdump -r" to turn it to ascii and 
then diff; probably some little script that integrated with a GUI tool 
like xxdiff would be nice.
