This implements the ability to negotiate a network connection over USB to iOS devices via Apple's USB muxer. This can work across platforms assuming iTunes or Apple Mobile Supprot is present. May work with open source usbmuxd/libimobiledevice on linux, but is untested.

Based on PeerTalk by Rasmus Andersson

This just provides the necessary code for the host (mac/windows) side to detect an iPad/iPhone & negotiate a connection to the device if it's listening.

1. iOS app sets up a TCP listener on a known port
2. Host app uses peertalk to wait for device to be plugged in
3. Upon plug, tell peertalk to establish a connection to the device with the port used in step 1
4. You'll have a ready to use TcpStream upon success

• Basic device listen protocol work started
• macOS/linux UNIX domain socket support
• Connect (network sockets) support
