The reason that memristors were so quick to market is that they were discovered while researching new fabrication processes. This isn't like, say, carbon nanotubes where they're able to make one or two in a lab. For memristors, they had a fabrication process from day one.

I heard a report on the Diane Rehm show that that's exactly what they're planning to do. The other approach that is forthcoming is convoys where multiple shipping vessels get together with one armed gunboat to protect them. Blackwater has come forth as a potential candidate for the security contract of future convoys.
