For usage in chroot()-ed environments where screen is required (e.g. running rtorrent as daemon), a detachable virtual screen without the need for special devices (i.e. running on nodev chroot) comes in handy. I happen to have written such screen alternative recently [1]. If you were interested in making it part of OpenBSD ports, I'd be honored.
