API to calculate drive distance between 2 US street addresses?
<p>Seems simple but users have no internet access.<br>
The application will be hosted internally on as Intranet site. The application will be able to make webservice calls to the internet.<br>
I tested and tried Mapquest.<br>
However all the other providers seems to assume the users are able to access the internet so their API's are javascript based with src tags pointing to internet URL's  </p>

<p>Any ideas?</p>
