Now there's a task for you! Figuring out how to combine a solitary scheduling tool with a highly distributed, cross-firewall collaboration platform (disguised as an Office 2007 application). Thankfully we've been doing this kind of thing since 2003.
Even better, we've just updated our product to make the link between MS Project and Groove event tighter. We've had more than a few customers download our free Groove workspace that includes a Task List. As a result, we've had more than a few customers ask how they can get the tasks they've been working on in Groove in to MS Project. Tasks lists typically start out small, and then grow.
Here's our screencast showing how to create an MS Project plan from a Groove task list. As you can see, it's eerily similar to creating an MS Project plan from a SharePoint task list.
Also like the SharePoint demonstration, you'll notice the 'Add New Tasks Created in Groove' checkbox. This feature allows IntelliGantt to recognize new tasks added via Groove and have them show up in MS Project, ready to be scheduled by the project manager. We feel this will be a handy workflow solution whereby people can enter their tasks or issues and project managers can put them on a timeline.
The free Groove task list has been available for a few months now. I think a few thousand of you are using it. This feature is absolutely compatible with the TeamDirection Groove task list-- you can start using it today (it's almost like we planned it :).
