Without redefining anything?

  STDOUT.reopen("|tee output")

I know nothing about io-tee, though what about this?

class IO
  class Tee
    attr_reader :ios
    def initialize(*ios)
      @ios = ios
    end
    def write
      @ios.dup.each do |f|
        f.write(str) rescue @ios.delete(f)
      end
    end
  end
end

$stdout = IO::Tee.new(STDOUT)
class Object
  remove_const(:STDOUT)
end
STDOUT = $stdout
