This is a step in the right direction for Microsoft, although a little confusing as the company already has three separate group collaboration apps with Net Meeting, Windows Meeting Space, and Groove Virtual Office (okay--we'll admit Groove isn't exactly a casual consumer-friendly app at $200). There's also some competition brewing in this space on the Web side of things, as we saw at the Under the Radar conference last week. Competitors like Yugma (previous coverage), offer nearly all these features (in some cases more), and have Mac support too.
