I've been making TV for 30 years. That alone doesn't make me an authority on what can be done with TV.
I don't think two lasers carrying TV is that hard, but then I've worked in the fiber networking for several years, so I may have a better understanding that you.
The fact that there aren't any reasonable responses to your proposal on what FIOS could do suggests that it is you that has no idea how it could work but the power of fiber must somehow make it possible.
This clearly shows once again your clueless about how something works.
I go back to my 8" water main argument. It doesn't matter what's on the outside if it all has to pass through a relatively small pipe to get inside your home.
In this case, delivering your final insult and saying that you're done is a declaration of no contest. Many of your previous "I'm dones" have ended similarly.
