Google has just introduced the Google Apps Marketplace

Google has just introduced the Google Apps Marketplace or one of his best ideas in a long time to attract developers to the key asset for companies.

Basically any developer will be able to create an application, upload it to the marketplace, selling to corporate users use Google Apps and Google as its distribution channel in exchange for 20% of the purchase price plus a $ 100 membership:

a) What do developers earn with this? giant distribution channel, tested, and with many established and corporate clients who would not otherwise access
b) Google is winning with this? A new ecosystem in which they put their infrastructure and expect to generate revenue .... beyond advertising
c) What do we win the Google Apps users? Added value to something quite basic and, like it or not, it's just a plugin for MS: Office

Would you expect the criticism? Microsoft expected to speak on the subject ... the design because we are not going to speak;)
