ionet provides a net.Conn and a net.Listener in which connections use an io.Reader and an io.Writer instead of a traditional network stack.

This can be handy in unit tests, because it enables you to mock out the network.

It's also useful when using an external network stack. At PayPal, ionet is used in PayPal Beacon. Beacon uses a Bluetooth Low Energy chip accessed over a serial connection. ionet enables the use of net-based code, such as the stdlib's [net/http]((http://golang.org/pkg/net/http/), with a mediated network.

ionet requires Go 1.1 or later, and is released under a BSD-style license similar to Go's.
