App Idea: Podcast Bookmarking

Here’s a smartphone app idea that is either a recommendation request, or a million dollar idea that you can steal and later repay me with a free copy of said app. Here’s the idea:

The app should be a standard podcast player BUT with the ability to bookmark some points in the podcast where it has useful information you’d like to zip directly to, later.

You should be able to shake the phone or hit a button at any time during playback to set a bookmark, and then review a list of bookmarks in the podcast that you can click and visit at any time in the future.

Good idea? Already bindun? Please let me know in the comments.
