Ok, does this hex mean anything to anyone?

It's the first line of a hexdump. It doesn't seem to map to any magic numbers or file headers. I'm stumped.

For reference, I've been scraping the hex on jwz.org for a while (and scraped everything in the wayback machine). It definitely looks like some kind of hexdump; the displayed chunks change over time. It probably means something, because:

<!-- mail me if you find the secret -->
<!--   (no, you can't have a hint)  -->

I have much more but I don't want to ruin the fun by posting it. Please email if you have an inkling.
