The biggest problem with peer is that you have to specify each and every
system you want to have participate in the scheme. With broadcast and
multicast you don't need to do that, they find each other. I prefer
multicast as it doesn't send messages to all systems even if they're not
participating. You have a much more targeted group of systems.
