I think Device Push should just be Push and Web Push should be something different to show it is different. Maybe something simple like PubSub since that's basically what it is. Oh, yeah - as usually, I don't really care on names that much :)

Push Messages are not intented to deliver large messages, nor in a low-latency fashion. They are more notification-style messages. The latency can not be controlled, since the actual message delivery, to the phone, is controlled by the actual Push Network. > > The AeroGear server submits messages, for a certain mobile app, to such a Push Network (like APNs or GCM). DifferentPush Networks have different limitations and restrictions, regarding message size, etc. Most Push Networks queue the message for offline devices (e.g. no connection, no roaming or device switched off). Once they are back online the message are delivered. Since these messages can become stale the Push Network allow to specify an expiry time. > > Supported client platforms > > Initially we are supporting the following platforms: > > Android > iOS > Note: The above platforms includes hybrid containers, such as Apache Cordova! > > In the future we may add support for more platforms, such as: > > Firefox OS > Blackberry > Windows > NOTE: One thing to have in mind, that there will be (eventually) a JS API, which allows a server to deliver messages to a JS application, deployed on any phone. However, it may take very long to get a unified standard, that works accross the different devices.

We could follow this emerging spec from FFOS (https://wiki.mozilla.org/WebAPI/SimplePush) which they plan to implement in FF mobile and desktop later this year. sounds good We would need to build the server side piece into our unified push server yup - that's not hard; it's similar to what we have for iOS and Android; It just uses a different PushNetwork to submit to; bits but I think the effort would be worth it to provide a cross-browser solution for push on the web which could be transitioned to the native browser push when ready. early on ! :)) sounds good! > Web Push > The Web Push allows a low-latency message exchange between connected (read: online) clients and the server. This is usually realized with technologies like WebSocket (or robust fallbacks like SockJS). Once a client application connects, it can exchange (receive and send) messages with the server (and other clients). Messages have no restrictions in terms of size of content (JSON, binary). While technoques like SockJS provide a socket connection between the client and the server, it is desired to have a more high-level API, to be used for the communication (e.g. Stomp). > > Initially, Clients that are offline are NOT receiving messages.
