BTW I also suggest you use a proper string member rather
than simply alias a null terminated string with a char
pointer. It's rather dangerous.

What could happen? The only thing I can imagine is using the
char pointer to modify the string literal. This can be fixed
by using a pointer to a const char.

    void
    muckItUp()
    {
        char doh[] = "How long will I exist?" ;
        Singleton::GetInstance().SetName( doh ) ;
    }

I wouldn't like to use the singleton after a call to muckItUp.
