Systems and methods for dynamic access to program features

At least one server computer system comprising:

• computer-readable memory storing instructions that are capable of being executed by the at least one server computer system, the instructions when executed by the at least one server computer system resulting in the at least one server computer system being capable of providing, at least in part, in operation of the at least one server computer system, in response at least in part to at least one request, at least one service, the at least one service comprising at least one word processing feature, the at least one word processing feature being accessible via at least one remote computer system;
• the at least one service being provided based upon a subscription, the subscription being capable of being established via at least one user account capable of being created, at least in part, using the at least one remote computer system;
• the subscription being associated with one of a plurality of subscription levels, the plurality of subscription levels including at least one relatively higher subscription level and at least one relatively lower subscription level;
• the at least one relatively higher subscription level being associated with at least one set of features, the at least one relatively lower subscription level being associated with at least one other set of features;
• the at least one set of features including at least one additional feature compared to the at least one other set of features, the at least one additional feature being capable of being provided, at least in part, via at least one application that is capable of being provided, at least in part, via download, from the at least one server computer system to the at least one remote computer system;
• the at least one relatively higher subscription level being associated with at least one relatively higher subscription fee relative to at least one relatively lower subscription fee associated with the at least one relatively lower subscription level;
• wherein:
• the at least one server computer system is capable of providing, in response at least in part to at least one other request from the at least one remote computer system, at least one subscription-based unlimited music streaming and audio file download service to be provided to the at least one remote computer system for playing via at least one downloadable media application;
• the at least one server computer system is capable of periodically providing to the at least one remote computer system updated user access control-related data to be stored at the at least one remote computer system so as to permit dynamic control of user access to streaming media content that is capable of being provided to the at least one remote computer system from the at least one server computer system.
