Packet8 looks like it has locals in 47 of the "lower 48" with local access
coming to Hawaii at some point in the near future. I checked - in some 
states like Ohio they only hit the big cities - on the other hand, out 
here in California I can even get a number local to my house because they 
have Victorville exchanges (and while there is a relatively large 
population here, we're still mostly rural and we are in the middle of the 
Mojave Desert :)

Yeahbut what if I am connected to my VOIP account from my house, and then 
I go on vacation and take my phone with me?

I don't think the 911 obstacle is impossible to overcome, but there are 
some issues that still need to be addressed.
