In that case you would be well catered for by.....

class buffered_observer : public observer
{
        std::stringstream write_stream_;

protected:
        std::ostream & out() { return write_stream_; }

public:
        std::istream & write_stream()
        {
                return write_stream_;
        }
};

Note: I am assuming that the multiplexor will not reenter the observer
on another thread during an on_xxx call

Now your example could become

class my_observer : public buffered_observer
{
public:
        void on_connect()
        {
                ...
                out() << "Hello World" << std::flush;
        }	
};

I will take an ostream over writen any day.
