I think this could be used for both incoming and outgoing requests. From what I gathered reading the docs and API, this doesn't actually forward your request to the API, it just keeps track of rate's and limits, leaving the actual limiting up to you. Its a microservice that keeps track of limits for you, and is highly distributed.

Basically, and I can be totally wrong, what it looks like is you send a rate limit request stating I'm doing 1 hit, I can do 100 hits a minute, am I over limit? Gubernator responds with either a status 0 (no, under limit), how many requests you have left, and the time the rate limit will reset. Or it will return 1 (yes, over limit), the time the limit resets, and you then have to hold your request until the reset time.

So you could use this as a self imposed rate limit for external services. I think the confusion is from the announcement, it sounded like this was a proxy type service that would hold your request until the limit was met. From what I read, it looks like you ask for the rate limit status, then its up to you to actually limit your requests.
