I made a tool to convert a podcast's RSS feed into a webpage on which episodes can be easily streamed.
When you visit the page, you'll see a box in which to paste the RSS feed's url:
Stick in a feed's RSS URL, and you get all available episodes in a list, reverse chronologically by release date:
Titles are links taken from the feed's metadata. Images are hotlinked from the host. Click-to-listen links bring up an embedded player:
The feed is stored in the page's URL, so it should be sharable. Currently no way to identify a given episode, but you should be able to do that with the episode title links, which should go back to the source.
If you use it, let me know!
