Also, I have a question...

    results = select([@sock, STDIN], nil, nil)

        for input in results[0]
          [...]
        end #for
      end #if


Instead of doing a for loop - just do "results[0].each", which is more 
idiomatic.
The question is, what does "select" do ? rdocs aren't helpful, and I 
don't understand that bit of code.
