No, we're discounting what doesn't make sense.  The guy wants
everybody to evaluate his nifty system without supplying the program
for analysis.  This doesn't wash.  He's assuming we can't figure out
how the program works.  You're not allowed to make that assumption.

I see nothing in the article that indicates his system IS keyed.
There is nothing in the article to indicate how the system actually
works, and until the guy explains his algorithm he is selling snake
oil.

I don't believe you.  Explain how this makes a system harder to break.
The decryption process has to work on any message, so it has to
somehow discern something invariant in the message that leads to the
original plaintext.  The cryptographer is free to do the same.

Ok, explain to me what new concepts I'm rejecting here.
