Vibed is in D1? Are you sure? I can't seem to find any mention of 
that, it works with the current DMD, but then again I've never 
tried to compile a D1 program with it.

Thhanks for you're answer, but I was looking for something a 
little more comprehensive, something that will work with WebRTC, 
that means binary or encoded messages, audio and video 
communication. It may seem hard to understand of you read the 
official documents but there are server examples written in C, 
C++, Java, Python, Erlang and node.js all open-source. I was 
hoping to find one written in D too. Oh well...
