title: Redis client to listen to SET and DEL events
body: <p>I can easily use Redis Pub/Sub functionality to send messages between Redis clients, but I am having trouble finding the syntax to listen to basic Redis events like SET or DEL. I want to create a client that will listen for basic Redis events like the udpating of a key/value pair, but none of the Pub/Sub libraries that I can find give examples of how to listen to basic events like deletes or sets.</p>
  
  <p>For example, I am looking for something along the lines of:</p>
  
  <pre><code>var redis = require('redis');
  var client = redis.createClient();
  
  client.on('SET', function(result){
  //this will be invoked when any key or a specific key is set
  }
  
  client.on('DEL', function(result){
  //this will be invoked when any key or a specific key is deleted
  }
  </code></pre>
  
  <p>does this high-level code exist yet?</p>
