Quite a loaded response there, BRooDJeRo. Did I hit a nerve? My apologies. I too miss the homework, in particular what LAN actually means. Provider maintenance isn't an issue, and the connection between two LAN machines is nearly always superior to that of two over the internet. Sandwich indeed.
Now that's dealt with, I should probably mention this isn't my video. I am relaying it for someone. This was two local machines, not over the internet. I know for a fact that the two machines he uses are good spec. If you need more information, don't hesitate to ask.
