For the "Better Together" New Day Launch demo that we are doing for the Developer Track in Atlanta on February 8th, we are demonstrating a type of application classified as an Office Business Application. This type of application is the closest description that I have seen to describe the types of applications that ThreeWill builds (Office 2007 Client (Groove, InfoPath, Project, Outlook), SharePoint 2007 (WSS v3, MOSS 2007), and Workflow Foundation).

I wanted to post up some additional links about the subject from Microsoft so you can learn more (thanks to Kirk Liemohn for sharing these).
