This is very useful thing. If you require customers to register their 
location, and use their service, you 'solve' the problem'.

Unfortunately, not all PSAPs have 10-digit number you can dial. Many of 
those that do have it as 'general access line' which isn't answered by 
emergency response personnel.

Based on what, magic?

Repeat after me: It is not possible, to retrieve geographic location based
on IP address.
