In my mind, 'Groupware' is just an old term for the following functions: - shared calendars (with scheduling, availability & conflict resolution) - global, shared address books - server-side email Unfortunately the most popular options for the average company to utilise these functions is restricted to using closed source solutions where you manage a server yourself (Microsoft Exchange) or closed source solutions where another company manages the server for you (Gmail and Google Calendar). Its a shame that more open protocols and servers haven't taken off in this space and provide competition. However as many companies have previously tried and failed to deliver a viable product its unlikely anyone else will step up to provide such a solution.
