So to be clear, I do vote a Initial like authentication scheme in Retry, as I hope I have stated earlier. But @nibanks concern is valid. I just don't think they have to be mutually exclusive:

You can have tail authentication tags and have other data that is fast for hardware to verify even if the filter is not perfect. I'd rather not rely on UDP headers for anything but IP routing.
