One more thing: I suspect the following will not work, with a glance
at your code: Change 'U' into:

    struct W {
        explicit W(int) { }
        W(const W&) = delete;
        W(W&&) { }
        W& operator=(const W&) = delete;
        W& operator=(W&&) = delete;
    struct U {
        U(W&&) { }

Now with shared_ptr and allocate_shared, this will compile just fine:

    p1 = allocate_shared<U>(Allocator<U>(n1, m2), W(1));

With root_ptr, I'm guessing you would change it to something like:

    allocator_type a1(n1, m1);
    p1 = new (a1) node(a1, W(1));

Your implementation looks like it will try to copy W which would fail
to compile.
