I see; I was not aware of that service. However, looking over the docs at the link you provide, it looks like its no difference for the mobile device. Mobile apps would still register with the native platform push notification service, store that at your server service, and receive messages from the native platform push notification service. That plugin would still be Phonegap interface for these operations. The only difference would be, from your publishing side on the server, using Amazon SNS instead of separate platform services.
