@aeromaxx Are you planning to work more on this? I have digged into it a bit on my own, out of curiosity.. If you are motivated, and able to get proper build environment set up etc, I could give you some pointers.. (if not, I could continue and make my draft into a complete PR)

@aeromaxx Are you planning to work more on this?

@albertony No I couldn't get a proper build environment to work, and I have never used Go before, or written anything using it, and I didn't understand the confusing errors I was getting, or how to fix them... If the errors actually made sense, I could have probably got it work.

Closing this in favor of #5367.
