This is on our radar, and we are working on it. Very approximate roadmap is like this:
* byte channels
* sockets
* http protocol (client & server sides)
* #ktor backend, may be okhttp, retrofit, etc to follow for Android users
* async SQL connections and what not
Currently using Netty with #ktor and coroutines works quite good, but the gateway from Netty world to coroutines and back is so painful…
