Looks very beautiful. Almost like Yammer that's centered around projects only. Do you plan to add more features, or just want it to be a project status updater? For what it's worth, I find many project management tools confusing; always seems like they take too many steps to just get your tasks in there and updated. Still, at least a to-do list under each project would be useful.

What are your pricing plans? An installable, roll-your-own-server option would be cool...
