Tom,

What's the real benefit of such implementation of IP-in-UDP compared to the approach as described draft-xu-intarea-ip-in-udp-03? Save one UDP port number?

Best regards,

>    This specification describes Generic UDP Encapsulation (GUE), which
>    is a scheme for using UDP to encapsulate packets of arbitrary IP
