Brian does a great survey of the various application stores that are cropping up left and right from every vendor and catering to every different type. Definitely an interesting perspective of the various groups working under the radar to evolve current and next generation integration for billing and distribution. If you write apps for the web, desktop, or even mobile - this is a great one for you!
