I just found this presentation today:

**[ZeroMQ with NodeJS](https://www.slideshare.net/fedario/zero-mq-with-nodejs "ZeroMQ with NodeJS")** from **[Fernando Sanabria](http://www.slideshare.net/fedario)**
I was considering ZeroMQ since a couple of weeks ago, but this file completed the sale in my case.

Interesting enough, the author lives in Buenos Aires, and it was a presentation during a NodeJS meetup.
