 That'll start a cable server on port 28080. Remember to point your client-side setup against that using something like:
 `App.cable.createConsumer('ws://basecamp.dev:28080')`.
 
+Beware that currently the cable server will _not_ auto-reload any changes in the framework. As we've discussed, long-running cable connections mean long-running objects. We don't yet have a way of reloading the classes of those objects in a safe manner. So when you change your channels, or the model your channels use, you must restart the cable server.

 Note: We'll get all this abstracted properly when the framework is integrated into Rails.
