I don't believe anyone is actually using the LOC RR, but maybe I'm wrong. This seems like the best way to store this type of data. I could see CDNs being able to leverage this along with edns-client-subnet to decrease page load times significantly.
How is knowing the physical location going to decrease page load times? Hint: I live all of 3 miles from my office. But home is deep in Comcast cable territory, while office is hanging off connections to Ashburn and Atlanta. So from home to office, packets have to go 400 miles north or south, then back. If Akamai decided to serve me a page at home out of the Akamai servers at work because it's only 3 miles away, it just added 25ms to each RTT it has to take. Which is why Akamai (and any other *sane* CDN) make their decisions based on network topology, not physical location....
