COMP 405 Spring 2014	GAE Channels

"The Channel API creates a persistent connection between your application and Google servers, allowing your application to send messages to JavaScript clients in real time without the use of polling. This is useful for applications designed to update users about new information immediately. Some example use-cases include collaborative applications, multi-player games, or chat rooms. In general, using the Channel API is a better choice than polling in situations where updates can't be predicted or scripted, such as when relaying information between human users or from events not generated systematically."  (from Java Channel API Overview)
