<various "We should port BSD" quotes>
Someone did a bunch of patches to one of the BSD's some years ago. I know, I saw it. I'm pretty sure I bookmarked it but as per usual, when I want to find the thing I can't... ah, there it is. Hmmm... it was the FreeBSD stuff. Maybe someone (else) can have a shufty and see if it's a good starting point. -- Rod
