 The problem with location tracking via IP is that, often, the entity who is the current "owner" of the IP at the time is not the same entity that has that IP space registered with ARIN. For example, I plugged in the serial side IP of one of the IP T1s in my office, and what comes up is my provider's corporate headquarters in MA, not my office in NJ. 

 There are, however, other ways to do this. You could opt to have the user choose what "location" they're at and then drop a cookie on the user's browser at that location that will allow the browser to "remember" what location it's supposed to be. This isn't without its drawbacks either. There are many users that have cookies disabled because of privacy concerns, but at least with this approach the barrier to get it working again is generally in the hands of the user or their administrator.
