Right now, any member of a Groove workgroup can invite a new person to join. Similarly, any member can uninvite any other member. The workgroup is instantly dissolved and reformed without the uninvited member. The new group also gets a new security key. This process is transparent and automatic.
Groove has an uphill battle on other fronts.
It goes against the corporate trend towards more uniformity on desktops, notes Dwight Davis of Summit Strategies , a Boston-based consulting firm. You could end up with a great diversity of configurations on employees' desktops, making them very difficult to manage and maintain, says Davis. Groove's fat client architecture also raises issues of performance and bandwidth consumption. While it's still too early to determine what problems may arise here, it's an area that warrants watching and testing. Furthermore, in the wake of the Napster lawsuit, corporations may be wary of P2P technology altogether.
