Kafka REST proposal

REST interface for Kafka

Taking inspiration from the projects page...

I think it would really useful and pretty simple to add a REST interface to Kafka. I could see two possible routes (not mutually exclusive): using HTTP as a dumb transport layer, and using it with different media types for application-friendly consumption of messages (JSON, XML, etc). The dumb transport would be useful for languages without first-class clients, and the content-type extension would be useful for writing web apps that are Kafka-enabled.
