Hi Charles,

I actually have lots of data on this, since I ran tcpdump on every major
run when I was gathering data. Each tcpdump output file is about 20 MB.

That's the good news. =


The bad news is I don't know if I can release that specific data. My =

guess is that I'll have to cut over to a totally isolated subnet and =

rerun things. =


However, if such data can be released, and if there's enough interest in
looking the tcpdump output, I'd be willing to go to the efforts of doing =

so for those who'd be interested in looking at the tcpdump data.

So I'll investigate further. =


Best Regards,

	-dwight-
