Great, thanks.

Hm, I'll have to think about the API.  I suppose the most simple 
approach is to just add accessors for duration and ip_address (with a 
'nil' value by default).  In practice, then, your code would look like this:

if p.ping?
    puts p.ip_address
    puts p.duration
end

How does that look?
