This would miss the second major improvement of RDS, namely removing the need for the application to perform timeouts and retries on datagram packets. If Oracle ran over UDP/IP/IPoIB it would not be guaranteed a loss-less reliable interface. If UDP/IP/IPoIB provided a loss-less reliable interface it would likely break or affect other UDP applications which are expecting a flow controlled interface.
