title: How to create a virtual device in linux?
body: <p>My question is pretty much the same as -
  <a href="https://stackoverflow.com/questions/2080892/how-to-create-a-virtual-file">How to create a virtual file?</a>
  except I want to do it in Linux instead. I imagine what I need to do is create a virtual device and point the application logging to that device. I'd like to write the device in python or ruby or something else interpreted, if possible.</p>
