A system for managing use of an item of digital content based on usage rights associated with the item of digital content, the usage rights being enforceable by a user device, said system comprising: an access list defining a trusted community of content users subscribed to a content service;a co
1. A system for managing use of an item of digital content based on usage rights associated with the item of digital content, the usage rights being enforceable by a user device, said system comprising: an access list defining a trusted community of content users subscribed to a content service;a content device configured to associate digital contents with the content service;a policy device specifying a license request process to handle a license request made by a user that is not subscribed to the content service, the license request process permitting issuance of a license to a user that is not subscribed to the content service upon payment of a fee; anda license device configured to issue a license to a user, wherein the license device is configured to: receive a license request from a user device,determine based on the access list if the user is currently subscribed to the content service, andissue a subscription license to the user if the user is currently subscribed to the content service, the subscription license granting the user the right to use digital contents associated with the content service, including future contents, and if the user is not currently subscribed to the content service, and the request is for use of a digital content associated with the content service, executing the license request process to issue a usage license to the user for use of the requested digital content upon receiving a fee. 2. A system as recited in claim 1, wherein the subscription license includes a condition for use of digital contents associated with the content service. 3. A system as recited in claim 1, wherein the usage license is associated with the specific item of digital content requested by the user. 4. A system as recited in claim 1, wherein the subscription license is associated with all digital content associated with the content service. 5. A system as recited in claim 1, further comprising a management device configured to at least one of add and delete users from the access list to thereby change users within the trusted community. 6. A system as recited in claim 1, wherein the usage license permits the user to use the requested digital content in a specified manner. 7. A method for managing use of an item of digital content based on usage rights associated with the item of digital content, the usage rights being enforceable by a user device, said method comprising: creating, using a computing device, an access list defining a trusted community of content users subscribed to a content service;associating, using a content device, digital contents with the content service;specifying, using a policy device, a license request process to handle a license request made by a user that is not subscribed to the content service, the license request process permitting issuance of a license to a user that is not subscribed to the content service upon payment of a fee;receiving, at the license device, a license request from a user device;determining, using the license device, based on the access list if the user is currently subscribed to the content service; andissuing, using the license device, a subscription license to the user if the user is currently subscribed to the content service, the subscription license granting the user the right to use digital contents associated with the content service, including future contents, and, if the user is not currently subscribed to the content service, and the request is for use of a digital content associated with the content service, executing the license request process to issue a usage license to the user for use of the requested digital content upon receiving a fee. 8. A method as recited in claim 7, wherein the subscription license includes a condition for use of digital contents associated with the content service. 9. A method as recited in claim 7, wherein the usage license is associated with the specific item of digital content requested by the user. 10. A method as recited in claim 7, wherein the subscription license is associated with all digital content associated with the content service. 11. A method as recited in claim 7, further comprising at least one of adding and deleting users from the access list to thereby change users within the trusted community. 12. A method as recited in claim 7, wherein the usage license permits the user to use the requested digital content in a specified manner. 13. Computer readable media for use in a system for managing use of an item of digital content based on usage rights associated with the item of digital content, the usage rights being enforceable by a user device, said media comprising: instructions for creating, using a computing device, an access list defining a trusted community of content users subscribed to a content service;instructions for associating, using a content device, digital contents with the content service;instructions for specifying, using a policy device, a license request process to handle a license request made by a user that is not subscribed to the content service, the license request process permitting issuance of a license to a user that is not subscribed to the content service upon payment of a fee;instructions for receiving, at the license device, a license request from a user device;instructions for determining, using the license device, based on the access list if the user is currently subscribed to the content service; andinstructions for issuing, using the license device, a subscription license to the user if the user is currently subscribed to the content service, the subscription license granting the user the right to use digital contents associated with the content service, including future contents, and, if the user is not currently subscribed to the content service, and the request is for use of a digital content associated with the content service, executing the license request process to issue a usage license to the user for use of the requested digital content upon receiving a fee. 14. Media as recited in claim 13, wherein the subscription license includes a condition for use of digital contents associated with the content service. 15. Media as recited in claim 13, wherein the usage license is associated with the specific item of digital content requested by the user. 16. Media as recited in claim 13, wherein the subscription license is associated with all digital content associated with the content service. 17. Media as recited in claim 13, further comprising at least one of instructions for adding and deleting users from the access list to thereby change users within the trusted community. 18. Media as recited in claim 13, wherein the usage license permits the user to use the requested digital content in a specified manner.
