Commendo.com‘s Voyager is an application that will:

“Assemble content in a different way in a personal library”. Experience in Enterprise Mashups. Look at web as a content repository for your personal use.

This looks really neat, though seems there may be challenges for turning this towards commercial use since the content you are nabbing is mostly copyrighted. HOWEVER, are they focusing on the developers creating a form of mashup API that is then distributed to others who are all using the content for personal use – clever and I think fully copyright cool. …I’m not sure if this is possible though and I don’t think it’s the key idea.  They are geared to users not developers?

Allows personalization of the mashup and content experience.
