title: Binary "tail" a file
body: <p>I would guess most people on this site are familiar with tail, if not - it provides a "follow" mode that as text is appended to the file tail will dump those characters out to the terminal.</p>
  
  <p>What I am looking for (and possibly to write myself if necessary) is a version of tail that works on binary files. Basically I have a wireless link that I would like to trickle a file across as it comes down from another network link. Looking over the tail source code it wouldn't be too hard to rewrite, but I would rather not reinvent the wheel! This wouldn't strictly be "tail" as I would like the entire file to be copied, but it would watch as new bytes were added and stream those.</p>
  
  <p>Ideas?</p>
