Ah, the power of Google Blog Search.  While checking out the most "revelant" tags regarding blogs posting about Ken Wilber, ran across this article on the Institute for the Future, and a quick reference to a LOT of theories of everything.

Other Theories of Everything presented included:

    * A Brief History of Everything, by Ken Wilber
    * Spiral Dynamics
    * Consilience, by Edward O. Wilson
    * The Great Chain of Being, by Arthur Oncken Lovejoy (1873-1962)
    * The Nature of Order, by Christopher Alexander [Book one, Book two, Book three, Book four]
    * The Universe in a Single Atom, by the Dalai Lama
    * TRUTON (The Rational Unified Theory of Nature)

Also, then get referred to Rudy's Blog, who appears to have published a book called The Lifebox, the Seashell, and the Soul.

Don't know if this is good or not, but I'm pointing you to it.  I should do a review, but I don't really have time - so if someone wants to give a brief summary of the whole Wolfram-geek-spiritual point of view these guys are coming from, that would be cool.
