I like it. From a look at the slides I think David and Jonathan's header format looks easily understandable, simplistic, while being extensible in the same way as the IPv6 header format is. It looks to be very straightforward to implement which means that implementations will have fewer bugs, different implementors are more likely to end up with compatible impementations (even in any tricky corner cases), and that an implementation should be easily doable even for the very smallest of devices.
