title: What's the intention of opencpu.org compared to other approaches?
body: <p>Lately I was pointed to <a href="http://opencpu.org/" rel="nofollow">http://opencpu.org/</a> . Nifty website, but after browsing for a little while I wasn't so sure where it is located in the R landscape compared to e.g. <a href="http://rapache.net/" rel="nofollow">rApache</a> or <a href="http://rpy2.bitbucket.org/" rel="nofollow">RPy2</a>.</p>
  
  <p>After waiting a long time for the server to come back I was finally able to read the architecture section, but that wasn't too comprehensive. <strong>I'm looking for a more detailed explanation of what OpenCPU is, how it is intended to be used, and how this compares with existing tools such as <a href="http://rapache.net/" rel="nofollow">rApache</a> and <a href="http://rpy2.bitbucket.org/" rel="nofollow">RPy2</a>.</strong></p>
