Just as an FYI:
In an interesting turn of events (e.g. multiple states
suing Vongae, multiple RBOC's now offering to make their
E911 infrastructure available to VoIP providers in the face
of ineveitable FCC madates to do so, etc.), Vonage is saying
that they will make their E911 "service" and "opt-out" option,
instead of an "opt-in" option.
