Apple Thoughts: Qik For The iPhone, An Official App

"The folks who first showed us video streaming live from an iPhone, Qik, now have an official (non-jailbreak) app available in the App Store."

Basically this is a way to share what you are doing, while you are doing it via a live video feed. It is a free app but requires you to sign up for a Qik account (also free by the way). The app runs on iPhone 2G, 3G, and 3GS devices on 3G or Wi-Fi networks. You can also embed the video into your webpage and according to what I've read, it works fairly well for what it is. There is a short review of it at iProng Magazine.
