title: google map key for gmap v3
body: <p>i have a question regarding googlemap api version3, 
  basically we are already using google map api driving distance and geo code functionality within our internal web application,  for  that we are paying for google on our google map key, </p>
  
  <p>so my question is on old google map v2  we did have to encrypt our map key and post back to google in order to get work geocode or driving distance,   and at the same way do we still have to encrypt the google map key with map api V3 ?   or we dont need the map key for google map V3 ? </p>
  
  <p>thanks</p>
