While I was out with the sinus implosion, I was thoroughly out, and slept most of the time, so I lost about half a week on my WPE study program. I'm back in the saddle now, and have new reading notes recorded on my wpe.php page. So far I've been concentrating on the three papers on future directions in Internet research. As you'd expect, they are a bit vague, and to my surprise they aren't rich in ideas suitable for dissertation topics. The focus so far is more on the changing environment of the 'net from its origins, and the need to supplement, extend or (gasp!) discard the end-to-end argument.
