This could have applications outside the narrow use case you've outlined. I encourage you to think about security in both directions: (1) protecting storage devices from computers, and (2) protecting computers from storage devices. This sounds to me like a product that I'd like to have built in to computers in sensitive locations, where I'm worried about users bringing in uncontrolled USB devices from home. Contrariwise, when I'm travelling, I don't trust any computer I don't own, so I'm loath to insert my personally owned USB device into it: in that case, I need your exact product.
