Actually, as I understand it in certain configurations the NDE packets 
can be generated and emitted by the DFC CPU. As I recall, certain 
netflow options and/or masks prevent this from happening, and require 
the RP CPU to either modify the NDE packets which the DFC CPU generates, 
or generate the packets itself.

IIRC things like src/dst AS number and other things you'd expect the RP 
to know, but the DFC to not, come into this category.
