A plugin to show a use they have viewed an asset, like a link to a reading or a video.

Does WPMU have a plugin that could indicate to a member if they had viewed an item. For example, on Lynda.com videos that have been watched are marked watched.

I am designing a course site and that functionality would benefit my users greatly. I've looked around but I don't see a plugin here that will get me there. Any thoughts?
