Today, with SimplePush and the Unified Push, we treat every channel as a "Mobile Variant Instance". Does that really make sense? * Imagine a web-app, that has subscribed to three channels: - mail - chat/IM - HR-system These are really three different applications (different buisness logics), while a "Mobile Variant Instance" is representing one "installation" of the APP (e.g. hr-iOS installation or hr-Android installation). Something like: - Mail - chat/IM - HR-System would be three different PushApplications, in the Unified Push server. That could have their own variants (e.g. Mail-iOS, Mail4Android,...) I think, that it's currently wrong to register multiple channels for a MobileVariant. Perhaps I am wrong, but why would the SimplePush variant of a "Sports App" require more than one "sports" channel? If we would allow multiple channels, I think, we are mixing concepts here. I come to this, when thinking a bit more about the "unification" of the Message Formats -Matthias -- Matthias Wessendorf blog: http://matthiaswessendorf.wordpress.com/ sessions: http://www.slideshare.net/mwessendorf twitter: http://twitter.com/mwessendorf
