Adaptive bit-rate streaming. Akamai has it, and wants you, the iPhone 3GS user, to have it too.
In layman's terms, this means video streams to your OS 3.0-loaded iPhone/iPod Touch with fewer stops and starts, using standard server hardware and ignoring how glitchy your wireless network is (*cough*AT&T*cough*). Adobe Flash already does this, albeit via a proprietary method that requires equally proprietary servers. Even better, Akamai's flavor of video streaming runs in a plain vanilla Safari browser — no special (meaning, Death Star-blockable!) app required.
