This is actually very cool and is something incredibly handy for managing failover/membership.
What I unfortunately don't understand is that there doesn't seem to be a library I can use to take advantage of this in my own application. If I have a program (in Go) am I expected to spin up my own serf process then communicate with it via socket? Is there an option for me to have serf live inside my application?
The Serf executable is actually just a wrapper around the `serf` library. That library is designed to be embedded in Go applications. Documentation for the library is available here: http://godoc.org/github.com/hashicorp/serf/serf
