Found an interesting article about some high level thinking on machine replication. The original article is from "IEEE Transactions on Robotics." but a synopsis can be found at Physics News: [
www.physorg.com]
I especially like the point about simplicity being an integral part of efficient replication and that they had study a lot of the defining elements of replication. Reminds me of those fractals which draw enormous complexity from very compact equations: z=z^2+c for the Mandelbrot set.
