The target should be checked before the system, as current-system is
always defined, and would shortcut the or.  But you can now safely
forget about this detail and use the 'target-x86?' procedure instead,
which comes from (guix tilers).

What is SPOF?

> +@item combination load-balanced and multicast style message routing

I'd replace 'combination' here with the 'combine' verb.

> +@item excel at both streaming (high-throughput) and job oriented

> +@item primarily in-memory (beyond a high-water mark messages are transparently

The imperative rather than descriptive verb tense is used elsewhere
here, I'd stick with it (integrate with ...).

Could you send a v2 addressing the above?
