title: Detecting random keyboard hits considering QWERTY keyboard layout
body: <p>The <a href="http://arxiv.org/abs/1210.5560" rel="nofollow">winner of a recent Wikipedia vandalism detection competition</a> suggests that detection could be improved by "<i>detecting random keyboard hits considering QWERTY
  keyboard layout</i>".</p>
  
  <p>Example: <code>woijf qoeoifwjf oiiwjf oiwj pfowjfoiwjfo oiwjfoewoh</code></p>
  
  <p>Is there any software that <b>does this already</b> (preferably <a href="http://en.wikipedia.org/wiki/FOSS" rel="nofollow">free and open source</a>) ?</p>
  
  <p><b>If not</b>, is there an active FOSS project whose <b>goal</b> is to achieve this?</p>
  
  <p><b>If not</b>, how would you suggest to <b>implement</b> such a software?</p>
