I found your website from poking around online and trying to find out more about Fon, as they showed up one day while I was running AirPort on my Mac.  After reading this, I searched on their website and found a link to their manual:

I have no idea if they put it up after you posted this story, but it'd be interesting to find out if their instructions provide as much rant fodder as their delivery did.
