But people are already working on more sensitive receivers. But, leaving that aside, if the IP phone has a battery inside it and if it can record previous GPS locations and if you move the phone outside to a new location, then it could remember the last GPS detectable location and use that when it connects to the net again.
There's a reason these kinds of capabilities aren't in VoIP "phones". That reason is *money*. GPS capability in the handset would raise the cost of low-end VoIP handsets by an order of magnitude, at least. Using battery-power for the GPS while not plugged into the line is a laugh. Think about what happens when the batteries run down, *before* the phone reaches it's final destination. Suppose it's in an airplane at the time. The 911 call shows a "location" of 37,000 ft _above_ the middle of Lake Michigan. Care to imagine the lawsuit when somebody *dies*, when 'emergency responce' didn't get there in time, _because_ the phone lied about where it was at? Note: this is all getting _fair_ afield from the chartered NANOG subject matter. I'll shut up.
