There is a policy-based pointer, based on the Loki SmartPtr, coming up for
review soon which can emulate an auto_ptr and allows deletion policy to be
specified as part of the 'storage policy'.

Also, see move_ptr: http://www.kangaroologic.com/move_ptr/

I only looked very briefly, but I don't see how your auto_ptr can be returned
from functions. Also, why do you need the m_Owner variable?
