Use of rights-managed content is enabled by a digital license that
includes the identity of the licensee. The licensee redistributes the
content by sending a package containing the content and the license to
another party. That other party obtains a license to use the content by
contacting a license server, and preferably pays a fee for this license.
During the contact with the license server, the licensee's identifying
information is uploaded to the license server, which allows the license
server to determine who distributed the content to the other party. The
license server can use this information to reward the original licensee
for having redistributed the content.
