I tried using enable_shared_from_this with virtual inheritance, just to 
see if it would work.  I couldn't get it to work.  The first barrier is 
that enable_shared_from_this is a templated class, and from what I 
understand is that two template instantiations of a class are two 
entirely different classes, so I didn't even try to use virtual on that.
Sorry, I completely missed that enable_shared_from_this was a template 
class.  Yes in that case it won't work unless possibly you did something 
like this

class TheBase : public enable_shared_from_this<TheBase>
{
};

class Base1 : virtual public TheBase
{
};

class Base2 : virtual public TheBase
{
};

class MyClass : public Base1, public Base2
{
};

But then you may need dynamic_casts somewhere to get the actual 
interface pointer you required later so don't know if that will be possible.
