1. A portable storage device for providing a controlled streaming of streaming digital content, the portable storage device comprising:
- a non-volatile memory comprising a device license and a license policy, the license policy comprising a quality parameter; and
a controller configured to receive encrypted content from a sending device;
wherein the controller is further configured to receive a device identifier from a receiving device over a physical connectionwherein the controller is further configured to compare the device identifier to the device license;
wherein the controller is further configured to decrypt the encrypted content;
wherein the controller is further configured to modify the quality of the decrypted content using the quality parameter; and
wherein the controller is further configured to stream the modified decrypted content to the receiving device.
