But none of these projects are far enough along to address the looming crisis. There's a prototype implementation of LISP, but nothing in production. PNA defines an architecture, but lacks an implementation. And Trilogy is in the relatively early stages of setting up collaborative working groups -- an actual architecture, much less an implementation, is a ways off.

I'm fairly confident the current challenges will be met, because there are enough bright minds concentrated on the problem, and at least one potential architecture exists. But buckle your seatbelts because there's likely to be turbulence ahead.
