Ok, I've figured out the answer to question 2:

    void call(Args... args)
    {
        boost::function< void() > bound_fn = boost::bind(f, args...);
        bound_fn(); // in effect the bound_fn will be stored in a queue for
later envocation by a different thread
    }

Interested in your comments on my other 2 questions?

Thanks again
Steve
