I have a rough draft of the OSPF method that I've sent to some of our commercial support subscribers before, but it's still a little rough around the edges.
The other method hasn't had any documentation at all yet, I'm not sure anyone has ever done that exactly as I described.
You could put up a bounty for the documentation if you want to speed it up. It will happen eventually, whether it ends up on the Doc Wiki, in our 2.0 book (when that gets going), but funding always speeds up the process.
