Yeah, at-least-once is definitely the way to go, sounds like you've got a good architecture around that.
Another nice thing I've heard with Kafka is that it can store all messages since the beginning of time (if you want) and you can replay them to retrieve all your MQ-related state. Does NSQ do that, do you know?
