In my opinion, before you can lay new ground, you need to fully understand everything that has come before. Therefore, we start off with a review of notable papers, publications, and presentations that we have been able to find so far.
In the interest of brevity, we will actually skip everything on the left-hand side of this chart. I encourage you to review all this material yourself (the entries can be found in the Bibliography), so that you can better appreciate what all it takes to do something like this correctly.
However, I do still have the forty-something slides that comprised this material, and plan on making them available via my web site at <http://www.shub-internet.org/brad/papers/>.
