Hi all,
I am a JGroups dev newbie, and decided to try to implement RAFT [1]
consensus protocol on top of JGroups. RAFT is at the core of etcd and is
gaining momentum, I think a JGroups implementation could be useful either
for JGroups and for people needing a pure Java implementation.

I was skimming the documentation and JGroups code and have some questions,
hope to start with the right foot:

- first, is there an "hello world" Jgroups protocol to start with? Is it
the EXAMPLE protocol?
- it's not clear to me if I have to code "inside" JGroups (i.e. create
things like RAFT_LEADER_ELECTION, RAFT_SUSPECT and similar protocols) or I
can code everything "outside", i.e. using the MessageDispatcher class
- supposing the former, if I want to base everything on TCP do I need to
start extending BasicTCP?

I have many more questions but that should be enough to start :)

[1] I am sure everyone already knows it, but here is the link if needed
