Need to work on this section, explaining people in clear words what the hell is this service!
The Salut service is a serverless communication service: you do not need to connect and authenticate to a central server in order to use it.
This kind of serverless messaging system is restricted to a local area network and an active Internet connection is not necessary.
The people that use this service inside the same local area network will be auto-discovered, and it will be possible to send them messages and files as with other services.
All the modern local area networks should be able to support this kind of service.
