I currently run a startup that sells an iPhone app through the App Store. I love that the App Store takes care of the work of charging users, collection of sales tax, basic reporting, etc. and just wires over the final revenue at the end of the month. I think it's been a huge boon to independent developers, who can focus on just building a product.
I'm curious if there's something similar for web applications with a paid subscription model. I know Google Checkout has subscription support but as far as I can tell, it's not as comprehensive as the App Store model. I was excited by the Chrome Web Store, which seemed to offer this service, but I definitely can't use a service that's limited to only one browser.
Just curious if anyone's seen anything like this. Anything I should take a look at?
