Thanks, I've been using that page pretty extensively as a reference too
and I have to say that it is definitely one of the clearest explanations
I've seen.  I think that my problem has been that I've been including
the outer type and length bytes when I hash the 'data'.  The WP page
implies that, but in the addled state that my brain's been in for the
past day or two while looking at all the RFCs, commentaries, and so on,
I overlooked it.

Thanks,
Anthony.
