Apps I'd like see in Google's MarketPlace

What is the Google Apps Marketplace?
"The Google Apps Marketplace offers products and services designed for Google users, including installable apps that integrate directly with Google Apps. Installable apps are easy to use because they include single sign-on, Google's universal navigation, and some even include features that integrate with your domain's data."

Basically it makes those using Google Apps for their domain have easy access to sign up for other supported web services.  It would also be an awesome way for open source companies to make money. Any open source product with a company behind it that offers a hosted solution could potential qualify...


What would I like to see in the Google Apps Marketplace?

Ubuntu One - why can't I add my entire company to using Ubuntu One in one click?  Better yet, if we get some more Gmail/Calendar-Ubuntu integration.

OrangeHRM -  Great open source Human Resources system, right and it's open source and provides a hosted solution.  Let's make it easy to have the Human resource system and google apps be in sync.  User get's let go, their account automatically gets suspendeded, etc.  User's calendar automatically shows leave, etc.

Likely more like SugarCRM, vTiger, or Alfresco...  Which open source projects would you like to see available in the Google Apps Marketplace?
