Alongside the reasonable point of 911 dialing being unavailable during service and power outages, the writeup mentions broadband over power lines as a possible solution to the power failure problem. (talk about your cognitive dissonance!) It also notes that VoIP customers may not be listed in the local phone book, causing problems with "major fast food companies" (do they mean pizza deliveries?), and that Tivo requires a POTS line for initial setup (which sounds like Tivo's problem, not VoIP's)."
egrep patterns are full regular expressions; it uses a fast deterministic
algorithm that sometimes needs exponential space.
