title: iPhone Map Kit cluster pinpoints
body: <p>Regarding iPhone <a href="http://pragprog.com/screencasts/v-bdmapkit/using-map-kit" rel="noreferrer">Map Kit</a> cluster pinpoints:</p>
  
  <p>I have 1000's of marks that I want to show on the map but it's just too many to handle so I want to cluster them. </p>
  
  <p>Are there frameworks available or proof of concepts? That this is possible or is already been done?</p>
