 Thank you. Very interesting story and useful info.
 I'm also curious about the signal generated from customers from MoCA 
(multimedia over coax) devices. How many neighbors would be sharing the 
same coax medium?
 Does anybody have a guess? I'm guessing neighbors that are connected by 
the same drop amp would essentially be on the same wire. I would really 
appreciate any info.

 Thank you.
