Yesterday the Groove team announced on their blog the change to Groove. They said, The name makeover is in concert with the direction the product is going. SharePoint Workspace will provide easy access to SharePoint content (or content from any server that implements the publicly documented protocols) in an effort to provide a seamless online/offline experience. It will also now be bundled with the Office Professional 2010 package.
I’ve used Groove some but ran into some limitations as I was running all 64 bit machines. The post doesn’t mention anything specific about running on 64 bit, nor have I heard any other news about it, hopefully this is another thing that will be updated, the same functionality on 32 bit and 64 bit. Stay tuned for more news about Office 2010 as it emerges.
