You're going to have to explain how that would work.
I think it could go a little something like this....
Press Release from the Digital Content Distribution Alliance (DCDA)
The DCDA, representing companies that handle 90% of digital content distribution of movies, music, gaming and books would like to announce the creation of the
ContentSafe™ program. This program represents the commitment of the member companies to guaranteeing consumers access to purchased digital content in perpetuity, even in the event that the original content seller is no longer able to provide that access.
To fulfill this commitment, we are also announcing the creation of ContentSafe LLC, an independent entity, funded by the member companies, who will mirror all digital content sold in their storefronts. Should a member company no longer be able to provide access to purchased content, consumers will be able to download the content from
ContentSafe for a period of one year and will be allowed to create local backups of their content that will authenticate via
ContentSafe servers. After the one year of content availability, ContentSafe will no longer provide downloads of the content, but will continue to provide authentication services indefinitely. At this point, the consumer takes over the responsibility of storing and backing up their content. Should a situation arise where ContentSafe is no longer be able to provide authentication, an unlock mechanism will be made available to allow the content to be accessed freely.
