1. A method for securely distributing content, comprising:

  • generating, at a server in communication with a network, a protected document package (PDP) including encrypted content or a link to encrypted content, a Publisher Key (PK) for decrypting said encrypted content for presentation of said content by an authorized user via a Limited Capability Viewer (LCV), and software instructions which, when executed by a processor at a user device of a proposed authorized user, cause said user device to generate a Content Consumer License Request (CCLR) identifying said PK, said authorized user comprising a user having a Content Consumer License (CCL) compatible with the PK to enable thereby said decryption of said encrypted content by said PK included within said PDP;

    propagating, via said network, the PDP toward at least one user; and

    in response to receiving from a proposed authorized user a CCLR identifying said PK, propagating a CCL compatible with the PK toward said proposed authorized user;

    wherein said proposed authorized user is an unauthorized user where received PDP license requirements are not satisfied;

    wherein said LCV is configured to restrict editing, printing and copying of said content.
