title: How to use Channel instead of Group when using django channels?
body: <p>I 'm trying to make use of the channels project (<a href="http://channels.readthedocs.org/en/latest/index.html" rel="noreferrer">http://channels.readthedocs.org/en/latest/index.html</a>) on django.</p>
  
  <p>While on the docs there is a good tutorial for building a Group-based websocket application(chat), I couldn't find something related to a simple push mechanism that will be client specific (so no need to use Group)</p>
  
  <p>Let's say I want to build a feed aggregator with various news providers and when a user visits the homepage and waits for all the feeds to get parsed, I want to send him informational messages about which one is being parsed by the server, while he waits.</p>
  
  <p>What I got now is:
  consumers.py</p>
  
  <pre><code>from channels import Group, Channel
  from .views import sort_articles_by_date
  from .soup import ProviderParser
  from .models import Provider
  
  
  # Connected to websocket.connect and websocket.keepalive
  def ws_add(message):
      Group("news_providers_loading").add(message.reply_channel)
  
  def ws_message(message):
      providers = Provider.objects.all()
  
      articles = []
      for provider in providers:
          Group("news_providers_loading").send({'content': str(provider)})
          parser = ProviderParser(provider)
          articles.extend(parser.parse_articles())
  
       sort_articles_by_date(articles)
  
  
   # Connected to websocket.disconnect
   def ws_disconnect(message):
       Group("news_providers_loading").discard(message.reply_channel)
  </code></pre>
  
  <p>routing.py</p>
  
  <pre><code>channel_routing = {
      "websocket.connect": "news_providers.consumers.ws_add",
      "websocket.keepalive": "news_providers.consumers.ws_add",
      "websocket.receive": "news_providers.consumers.ws_message",
      "websocket.disconnect": "news_providers.consumers.ws_disconnect",
  }
  </code></pre>
  
  <p>Though it works ok, I can't help it but feel that's a bit overkill(?)
  Is there a way to just make use of the Channel constructor, instead of Group?</p>
  
  <p>Thanks :)</p>
