Hi Eric,

When we are discussing the draft-ietf-netconf-udp-pub-channel, we find a conflict with current dynamic subscription design.
1. The dynamic subscription requires notification to use the same channel as the subscription.
2. The RPC does not have the input information about the receiver because the above assumption.

However, when we talk about the distributed data collection (multi data originators), the publication channel is always different from the subscription channel.
So either the distributed data collection does not support dynamic subscription, or current dynamic subscription definition may need modification.

What's your thoughts?
