I'm no hardware expert, but isn't this more or less the same thing as what PC/104 and PC/104-Plus standards have been providing for the past several years, except PC/104 is slightly smaller (3.6 x 3.8 in) and has a nice stackable (standard) PCI bus? Granted, I don't believe I've seen cards that have quite the horsepower as IBM's solution, but why not go with a standard that already exists?
