FACT: My Nokia N70 delivers MP3 files over HTTP. This happens when using the Opera browser on the 3G phone with 3G service. When I type the URL of a podcast directly into the phone's browser, the N70's player presents the file for immediate playback, emulating a streaming experience. Bundle this experience with O2's gigaplan, and I have podcasts on the go for around €54 a month. That assumes I consume no more than two gigabytes of podcasts each month. Roll all your podcasts into BuzzBoost and you can offer mobile-friendly pages for visitors--fast-loading rivers of podcasts.
Dave Winer thinks, "We just need a quick way to get an MP3 over HTTP. These cell phones, with built-in speakers even, are good at audio." Yep. I wonder how long it will take the broadcast industry to cop onto the fact that newer cell phones can receive podcasts.
