Well your concept of business model for mobile apps is nice.
With a communication server, a mobile app as CEOware can poll for others' available time slots for a meeting, broadcast agenda and make group appointment requests. Also the CEO can post important subjects for voting or requests for advice by members of the management board and have results fed back in no time.
In future, it might be useful to have alertware as mobile apps that signify important PC/Server events, even changes to a multi-user document can be brought to user group attention by wifi broadcast from a smart document management system to mobile phones.
