I'm working on a demo of UPS pushing to iOS, Android, Windows, as well as Firefox OS using our Cordova plugin.

But as you know, with FFOS it is not that simple - since SimplePush protocol allows to transfer just incremental versions, we are not able to deliver any interesting message.

UnifiedPush Server could be a correct place where we unify and shield our users from this limitation:

my idea is storing the message on UPS under the SimplePush endpoint URL. Once the message with version reaches the client, he would contact UPS to retrieve this message under a key ( pushEndpoint, version ).

The messages could have default built-in TTL to allow periodic cleanup.

What do you think?

Cheers,
