Multi-Threaded Socket Client/Server

[securigy]

I am looking for a complete/working example of MicroPython socket client/server on LoPy.
Is anything like that available? From reading this forum I realize that _thread is quite not the same as .NET/C# multi-threading capabilities I am used to, but I'd like to start from something that works instead of re-inventing the wheel...
Ideally, I'd like to have a script/library where socket/class that wraps it can be given a role of server or role of client at instantiation...
