You can use transform + ostream_iterator instead of for_each + print.

transform( m_data.begin()
         , m_data.end()
         , ostream_iterator<string>(cout, "\n")
         , boost::bind( &Base::to_String
                      , _1
                      , indent_value));

And instead of handcrafted loop for indentation you can use constructor of 
std::string.

virtual string to_String ( boost::uint32_t indent )
{
    stringstream output;
    output << string(indent, ' ') << m_value;
    return output.str();
}
