title: Preferred layer to create track (line) on openlayers
body: <p>Currently using openlayers as map ui on my web app. The problem is i confused with many different layer type supported on Openlayers (which mean good btw). So anyone can suggest a suitable layer for this?</p>
  
  <p>My goal is simple, i just want to create a layer which contain line as "tracking line" (let's call it "track") like what we can see here:
  <a href="http://oms.wff.ch/ol_track.htm" rel="nofollow">OpenStreetMaps Example</a> </p>
  
  <p>Right now currently using PointTrack and GeoRSS to display the track layer, also i have considered using KML layer now since it more versatile.</p>
  
  <p>The consideration to take:</p>
  
  <ol>
  <li>It must be fast enough to render on all browsers (especially IE8)</li>
  <li>It loads data from other source (such as kml or xml file)</li>
  <li>Refreshable</li>
  <li>Styleable (size,color,etc)</li>
  </ol> 
  
  <p>PS: attach a sample if available</p>
