I don't know the answer specifically to your question but I remember attending a talk which Van gave on pathchar last year. I've found the slides for that talk here: ftp://ftp.ee.lbl.gov/pathchar/msri-talk.{pdf,ps.gz} As I recall, the talk was quite mathematical (it was given to the Mathematical Sciences Research Institute after all!) gave a good background on how traceroute works and how pathchar is an extension of those ideas. Figuring out the contents of a talk from only the slides can be very difficult if not impossible but perhaps this might help you figure it out. You may also try looking at some of the other papers or talks which have been given by members of the Network Research Group at LBL.
