If this is done correctly, I think it means I can "new" MyBinarySerialType from the regular heap and it will work entirely outside of shared memory.  Likewise if I use segment.construct<MyBinarySerialType>()(...), then the whole thing should be created inside of shared memory.  Either way, the vector will allocate strictly to a piece of memory inside the size of the class.  

No, you need to write your own allocator. Interprocess vector is a 
standard conforming vector that supports non-raw pointers, nothing else.
