This is long overdue - my intention was to keep netcat-openbsd to
track the development of the openbsd one, but it appears not happened
that way.

Some of them was sent, but getting few responses.

I don't treat this netcat-openbsd a full fork even if it's targeting
an older revision at the moment. Also, maintaining patches are very
easy using the git-buildpackage[1] tools for Debian packages.

I think it is hardly possible to provide another tarball because
there's no way of doing that with current Debian infrastructure. But
you can apply those patches easily using quilt[2]. In Debian, patches
are applied automatically when extracting the source package using
dpkg-source.

No problem.
