Realize also that exceptional uptime is not easy to achieve. If you want to sell this service, you also need to have incredibly reliable infrastructure. Example: I worked at a VoIP company. A mishandled call by another carrier in the chain led to the death of a child (it took several minutes to actually reach emergency services in the right country). You don't want to advertise that your app is available when everything else has failed unless it always is.
