NATS is legit -- Derek Collison has experience in messaging systems going back a very long way. Cloud Foundry still has a bunch of NATS-based services because Derek was one of the founders of the first versions, back when Cloud Foundry was a VMWare skunkworks effort (VCAP). Disclaimer: I work for Pivotal Labs, a division of Pivotal, which contributes the largest amount of engineering effort to Cloud Foundry. Apcera is, nominally, a competitor. I should also mention that my understanding of CF's early history is based on accounts I've heard and might be flawed.
