Transformative Works: Everyone has my full permission to do what they like with the stories I have written. Podfic, art, whatever strikes your fancy! HOWEVER, most of my work has been co-written and I can only give permission for ME. Please abide by the wishes of my co-writers if their permission policy is different from mine. If they do not have a posted policy, I am happy to ask them.
On a personal note, podfic is not a medium that works well for me. I am more than happy to link to any podfic that gets produced to the fic it's written for and will be THRILLED if it happens, but I may not be able to listen and give you proper feedback.
