Software Question

Maybe somebody reading this can help me. I have a PC and an iPhone and an iPad. I download a number of podcasts and listen to them on all three devices.

I use a program called Roboform that stores all my passwords and keeps them in sync on all three. I use a program called Evernote that stores all my short little notes and keeps them in sync on all three. I'm wondering if there's a program that will store all the podcasts I download and keep them in sync on all three…and the "sync" would include tracking which ones I listen to and where I pause them. The idea would be that I could listen to half a Marc Maron or Gilbert Gottfried podcast (or whatever) on the computer in my office, then get on an airplane with my iPad and say, "Oh, I haven't finished that one! I think I'll listen to the rest of it" and then click and resume playing!"

Has anyone invented this and if not, why not?
