Here are a few notes from Dave Winer’s discussion panel at MIX on how to build the perfect podcast player (somewhat random and scattered):
Sync over the air
Record (and perhaps publish) podcasts
Sharing with friends
Receving recommendations
Multi-speed – e.g., listen at 1.6x
Making comments – send an audio response
In a standalone player, email me the links associated with the audio content
Player needs to have a web server in it
Plenty more was said but that’s all I felt like persisting. Dave shrugs off the big players and says it’s fine if they don’t get it because someone else can. But I wonder if podcasting is a big enough area to be more than just added features on the big players’ players.
