Yup.

My lack of experience on non-Intel is showing, red face glowing.

I didn't even consider that case.

I'm not a GPL (or BSD for that mater) lawyer ... Shakespeare was right.

What I don't know about IPv6 exceeds what I don't now about big endian
machines !
I had been following the mailing list for a while, but dropped off about a month
ago. I checked out the current code today and didn't see any checksum
code so I thought I had done something new. Sorry to pollute the list with a
poor clone of what had already been done.
