Just to share a few thoughts:

1/ How about just called an NDN node as an NDN node, instead of "producer" to avoid confusion?
we call a node producer when it produces data.

2/ regarding the question of whether a node would forward a received interest: since you asked "*will* a node forward", that sounds like seeking for a universal answer, I'm not sure one exists. Resilient networking needs nodes help each other out, but a specific decision can be affected by several factors 
- duplicate suppression
- the node in wrong position (e.g. further away from where the data might be residing)
- wireless network overloaded?
- local resource constraints? (e.g. low battery)

The forwarding strategy may also play an important role here.
