Roderick, I understand all your wishes and can propose followed solution:

1. We add ability to set up creator for categories in HierarchyMaintainer
2. You write you own RTCategory that derived from log4cpp Category and meet all your requirements - 
you hide from usage all functions that receive std::strings and expose those that receive rt_strings.
3. To use log4cpp in usual manner user should setup default creator as RTCategory creator and do 
following when obtaining reference on RTCategory:

class foo
{
    public:
      foo() : logger_(static_cast<RTCategory&>(log4cpp::Category::getInstance("foo")))
      {
      }

    private:
      RTCategory& logger_;
};

Please, comment this.

As for rt allocator in HierarchyMaintainer that is really hard and likely impossible, because I 
don't know how to rewrite HierarchyMaintainer::_getInstance in a way that it become rt. It uses 
std::string and I see no way how to avoid std::string creation...
