Google Apps Marketplace

Google implemented in my opinion a long-obvious mechanism. Now each developer has the opportunity to sell his online services through an easy and convenient store .
In a google blog, I identified the following conditions for adding apps to a store:

1. Actually develop your business-oriented web service on any platform.
2. Integrate your application with Google Apps
3. • Add single sign-on technology (eng. Single Sign On - SSO) using OpenID (mandatory) - eliminates additional logins and passwords.
   • Add various functions and methods of interaction with Google Apps through Google Data APIs (this is already an option) .
   • Create a file with the settings describing the process of installing the application and the subsequent cycle of the application's life (links for installation, configuration, support and entry), pay a one-time payment of $ 100 to add to the list of store sellers.
   
   In general, nothing complicated, standard procedures. I think potentially this decision can have a great future. And finally, a video presentation from Campfire One:
