As the article is entitled: Will It Work? I know that we have some very bright people working on weapons systems, but dayum! This sounds like quite the "steel on target" delivery package (assuming it works).

As an aside, I've been saying for some time now (thanks to Virginia Postrel) that enough important base inventions have been made already; most of the low-hanging fruit now will be in nailing together two disparate bases and making them work. Examples of this nailing include: TiVo (machine-readable schedule information plus content-based searching plus recording), Roomba (miniaturized electronics plus acceptable pathfinding plus drudge labor), and SABR (miniaturized electronics (again) plus cheap accurate laser rangefinding plus accurate timing plus ordnance equals boom).
