Never heard about it before you mentioned it, but I'm not quite sure what they are up to. Forking OpenBSD to .. move it into the direction of NetBSD/FreeBSD?

Also, the website is quite sparse and I couldn't find out if they use the same ports tree as OpenBSD. The latter is (see my comment in the same thread here) out of date for a couple of packages I'm interested in. Just like FreeBSD's.
