Unfortunately for now this can only work from services hosting all the content. Because podcasts are hosted on their own services/servers, this cannot be done. Hopfully this will change in the future…JT commented
I understand what Xavier is saying.
Podcasts are hosted on various servers, some websites list and access those servers via an address to play podcasts and therefore operate as a 'portal'. PodcastAddict would have to operate as such a site... Stitcher, iTunes, GooglePlay Music, iHeartRadio, Spotify, and some others operate as such 'portals' - although there are podcasts that aren't accessible (probably haven't been added/entered) on some of those portals.
Unfortunately, most of these portals don't support OPML (podcast list files) import or upload. So you'd have to add the podcasts you want manually.
Just some FYI's.

Even if it's web-based or a Chrome extension... this would be a huuuuge plus.
**Here's a "workaround" for anyone interested**
You can install CloudReady by Neverware on a USB drive and run Google Chrome OS, thereby allowing you to run Android apps 'on your computer' but not actually in Windows.
For running Android apps on Windows, you'd have to use Bluestack or others like it.
See YouTube for tutorials on how to access, install, and use.
