Channel API is for sending messages "downstream" to web browsers. It can't be used to send messages "upstream," except for the message "I just left."
XMPP can be used for bi-directional messaging, and also doesn't have to be hosted in a browser. But it does need the client to provide a Jabber ID, which can be problematic. If your client is purely browser-based it will be much easier to set up the Channel API + some AJAX posting to create a bi-directional messaging system. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
