Can Messagenius provide a locally installable fallback system?

Messagenius provides a locally installable fallback system as long as there is a network connection between the dispersed locations. It can be done by installing a local server, with the local Wi-Fi. To guarantee the network across multiple dispersed locations, one of the locations will have to work as the main server. Alternatively, it is also possible to do that each location has its own server, and they are federated among each other.
