I have done a LOT of work! I have changed the whole paradigm of the ntk console client and console bindings! I have changed it from peer to peer to server-client because there was no point doing it the other way, And that way was hard and I didn't really know what I was doing. I followed some IBM examples, And didn't try to extrapolate.

Browse Source 
I have done a little bit of work trying to resolve some compilation errors, However, I cannot check if there are any compilation errors now because my root partition is full, again. My compiler needs to do something with /tmp so I can only see a portion of the error logs, All of which are warnings up until the no space error.

I will do some more testing and debugging on my other machine, Help is appreciated, Enjoy!
