udpfacade
Small library that might be useful for transparent UDP forwarding or UDP/IP spoofing, among other things.
Currently supports UDP over IPv4.
This library differs from most others than implement this functionality in that it is able to exploit the security/reliability of Go's built-in IP Dialing and Writing instead of writing frames directly to the wire or directly using raw IP sockets.
It took a long time to trace through the source to find a way to allow this, so I hope some find this useful!
