Tom Krazit at CNET News – Google announces business app store for Google Apps:

"Scott Farquhar, CEO of software tools company Atlassian, showed how Google Apps can be integrated directly into his company's software development tools. For example, software developers using Atlassian's project-management tools can have Gmail, Google Calendar, and Google Chat applications integrated directly into the software development tool, so they don't have to leave that window to check their e-mail or chat with colleagues."
