You never can *delete* an object (in the sense of invoking delete()
operator), which is accessed through shared_ptr. It can be deleted by
shared_ptr's deleter only.
If you return to your clients weak_ptr's to a "living" object, they
probably will lock() that weak_ptr in order to access the object, and
the object will be deleted only after all the clients dispose their
weak/shared ptrs.
