What I would like to do, is take something like the Title, or a custom field and tell the Currently... plugin what that was. The idea is that everytime I post in the "Movies", or "Books" categories, it would update that plugin. Is there someway to do this with existing plugins, or is this somthing I need to look at creating? If there exists a partial solution, the getting data into the CurrentlyPlaying plugin, could you point me to an example?

I dont know if this is helpful, but at least you can add this to specific entries:
