Well, yes. I agree with you about the latency part although I don't know how much(I have no measure) latency it would cause, and whether it would be bothering or not. I have no answer for that.<BR>
I think there should be some conventions in applications. As an example in application A some specific interests mean that the interest sender wants to pass a parameter or anything. So receiver knows this and sends a pre-defined interest after sending a pre-defined data responding to the previous interest.<BR>
As far as I understand, this is one of the implications of being consumer driven. At least in this very architecture(NDN). Every flow should start with an interest. You cannot send a data packet with already no interest asked for it. Because there would be no breadcrumbs. There would be no pit entry. Therefore there would be no forwarding.<BR>

Sabet, I believe, this involves a high latency. I presume there is an<BR>
assumption that receiver would send another interest. Why would it do so?<BR>
What if it does not send that Interest?<BR>
