! this is a work in progress !

There are a lot of cloud-based solutions for a lot of different things, synchronizing your data, sending files, and so forth.
But more often than not, I would prefer a solution that can work without a server sitting somewhere in the cloud. In a lot of use-cases, my devices sit in the same network, or are physically close to one another.
While working on a cloudless synchronization app, I realized that this communication part better have its own project, because it was getting rather sizy.
Have you devices communicate directly with one another, e.g. over the local network (see LAPI.Providers.LocalNetwork).

Server:

Client:

• Register clients with a server using an OTP, ideally transmitted out-of-band (e.g. using a QR-Code)
• Built-in authentication to prevent connections from unknown devices
• Establish an encrypted connection via SSL using X509Certificates
• Discover devices on your local network via UDP broadcast, so you are not forced to stick to a certain TCP port

• More local area communication implementations, like
  • Windows Pipes
  • Wifi direct / bluetooth
