For the love of pubsub

I have fancied publish-subscribe middleware(pubsub) architectures for quite sometime. When we were still very new in CTS, I came up with a wild suggestion to try this for getting a data dump from a legacy system into our moodle instance. I was quite clueless about what this would entail in terms of development effort, but I could create a PoC setup within a few days which made me quite confident of being able to pull this off....
