Rookie question:
Is it as obvious as it may seem to simply have just the one imp on the consumer side of say a put_port (non-blocking most likely), and multiple producers can connect to that single imp?
Yes, they would all be the same item types, and yes they would all be handled the same way.
Not the same as an analysis_port. More like an analysis_port with the traffic flowing the opposite direction. 
Any issues I may be overlooking or missing?
