On: ZeroMQ instead of HTTP, for internal services

[swah]

What about interoperability with external services? With HTTP, you could just open your APIs to the world, when it makes sense.

OP here. In the blog post, I use a traditional HTTP routing library on the server, and I return HTTP-like responses. Since I didn't reinvent that part, it's actually pretty trivial to either use the same code and package it into a war file, or just fire up a Jetty in-process if you only have one server instance.
