It is always amusing to see people allude to the end-to-end principle to support their arguments, when in fact the end-to-end principle is either inapplicable to the topic at hand, or actually lends support to the opposite of their arguments.

LISP gains value as more of the edge is incorporated into the system.  This doesn't mean it has no value during intermediate stages of deployment.

There are cogent arguments to be made against LISP and LISP-like systems.  But none of those arguments have been raised in this thread, so far.
