Given the current state of this technology (requiring a STM and very low temperatures) I question how soon, if ever, this type of "computer" will become useful for independent nano bots, especially within the human body or other non-ideal environment.
However, for working on a molecular scale to control things in a lab, this technology seems to have more immediate promise.

Episodes will be broadcast as a series on ESPNU and ESPN2 after filmed at the competition in June 2008. This is the first notable progress towards televised combat robotics in years.
