Remember, though: What you're passing to ping() is not a host name, it's
a /node/ name.  A node name is an erlang atom and is therefore case
sensitive.  It's certainly derived from a hostname, and might seem at
first like it should be case insensitive as a result, but as Bengt noted
that would mean implying atom equality where they're not actually equal.
