Not only getting assistance from DARPA but also from the Santa Fe Business Incubator Program (http://www.sfbi.net/). For the few naysayers that are routinely saying Mark & company are just scientists and not good business men, I would say getting free or low cost aid in commercializing their product and low cost leasing of office/tech space, etc. is good business. Not to mention the added exposure (especially DARPA), that comes with it.
