Most landlines are crap. If the telcos could quit supporting the old, aging copper wires they would. I expect at some point landlines will go the way of the telegraph I know my company is dumping them and going strictly to a VOIP system.
So I would certainly hope Viasat-2 will provide a VOIP option for ALL parts of the country. I know I don't have one of the fastest Exede connections, but I can't imagine how the people in the middle of the country have had to deal with Exede-5 for so many years.
