[ic] Distance calcs based on 2 zips

[interchange-users@interchange.redhat.com (Victor Nolton)]

Right now we are using curl to query mapquest which is slow. As a 
temp fix we're storing the returned data in SQL to save from having 
to query mapquest all the time.

BUT it would seem to me that there has to be a solution out there 
where you can plug in 2 zip codes and perform a lookup to grab the 
distance between the 2 points. It doesn't seem that difficult of a 
concept. Right now we are compiling data slowly but I am also sure 
somewhere there is a database of this information already compiled.. 
Maybe not

US Zipcodes :)

Any pointers?
