Future of Music Coalition, Public Knowledge and New America Foundation’s Open Technology Initiative sent a joint letter to Chairman Julius Genachowski of the Federal Communications Commission on July 14, 2011.  The letter is a request to investigate the data cap policies of all ISPs, as recent anecdotal evidence suggests inconsistencies in polices around and enforcement of data caps on broadband connections.  The signees believe that such data cap policies, when unchecked and inconsistent, run contrary to the values and goals of the National Broadband Plan and its’ support of cloud-based applications and computing.
