Maybe there was no simple implementation of vnc for Raspbian 5 years ago, which is the age of the topic you have chosen to ressurrect.
If you go back and re-read the entire thread, carefully, from start to finish, as I just did, you will see why any networking-based solution is a no-go for the OP. It is clear that his reasons for wanting to do it this way are:
1) Because the networking port on his laptop doesn't work correctly. Details are there if you need to refer back to them.
2) Because he really just wants an excuse to build the thing. He's itching to do it (and has, now 5 years ago, done so).
A couple of other comments:
1) I wonder where Frank is today. Wonder if he ever reads this board anymore.
2) Great post by that Joe Schmoe guy!
