Thank you for the directions, I will read the source this weekend. I might as well write my findings, try to create a document specifying FChannel's protocol.
That'd be a sub-optimal solution, if I simply blocked access to html pages to code would still exist. I prefer to write simpler software that runs low on resources, so it's either forking and overhauling FChannel-Server (I don't know Go) or writing something from scratch (maybe taking some ideas from the original).
Let me help you, fedifren. Where do you plan to host it? Your usual computer, dedicated computer, virtual machine, or rented server? I recommend a dedicated computer for security or, if you don't have one, a virtual machine.
Once you got that covered, I can help you get a setup similar to mine in one afternoon (took me longer than that to do it, but I was still figuring things out, you probably saw the thread on /b/).
It doesn't have to be perfect from the start, it took me some trial and error to setup the server in a way I like.
