I don't see how you can derive that I think it difficult from what I posted... An e-mail listener in UNIX has existed for possibly as long as you've been alive. It's a mature technology. As the platform exists today, there is a listener in the iPhone, obviously, since it listens for incoming calls. More than that ... well, who knows what will happen?
That said, there are trade-offs - security, interoperability within the present platform framework, and demands that would need to be met in the form of resources for the system and resources from the developer of the platform. There's no such thing as a free lunch. At this time, those trade-offs have prevented "push" from being implemented.
The only thing that can be derived from that is - push isn't here now. It may not be here later.
