Discuss ideas like a default open license (such as cc:by) for remix as the norm for podcasts, if certain elements (e.g. particular powerpoint slides or images) need more restrictions (ie copyright) then make explicit notice of license at the most atomic level (e.g. on each slide within the .ppt). Given that it will take a long time to get all slide deck authors to do this before presenting in public, one option is to export sensitive slides as .jpg and add attribution (or copyright if absolutely necessary) to any sensitive slides in the deck.
