Another thought - I agree with the poster who quibbled about the length of the article in ONE regard. Your title. It is not accurate. You compensate for this fairly quickly by stating your goals. It was because I read that section that I at first did not feel any issues with the title, but on reflection, your title should reflect your goals more accurately, and it should reflect that you spend a great deal of space on setting this up to talk outside the LAN, and talk to Macs.
