The Terms of Use appear to be very restrictive. Not only does it have the "non-commercial" restriction, limiting its use to throwaway projects that are not expected to succeed, but derivative works are disallowed. > Unless otherwise specified, the Services are for your personal and non-commercial use. You may not modify, copy, distribute, transmit, display, perform, reproduce, publish, license, create derivative works from, transfer, or sell any information, software, products or services obtained from the Services. As far as I can tell, you are free to admire the Concept Graph from a distance, but not to build anything on it.
