Groove networks provided a ""virtual office"" through software that allowed teams of people to work together over a network. Groove software offered organizations both a desktop application for joint work and a set of customizable, open collaboration capabilities that enhance the utility and value of existing solutions. Groove Networks was acquired by Microsoft in March of 2005, and has been re-released as a software. See http://office.microsoft.com/en-us/groove/default.aspx
