If the solution were bought off the shelf, there would be no need for
NASA Ames. Therefore...
Actually, what they want is something that can be claimed to evolve
apace with their spreadsheeted extrapolations of user needs for the
next 5 and 10 years. These extrapolations more or less follow Moore's
law applied to things like current storage requirements, so it's always an
interesting process keeping ahead, given NASA's acquisition process.
