Why are you still using IPv4 data link types (such as 0x800 for ethernet) ? That'll make your protocol safer to deploy and you won't be constrained to use any header format compatible with IPv4. > @ I'm not sure if you're aware of this, but there is an IPv6 being > @ developed by large number of people. > > I have been at this over 20 years...I am very aware of IPv6. > Have you ever seen some of the "private" opinions about > IPv6 from some of the experts that designed it...???

I think you'll find they'll let anybody submit anything as an informational RFC or an internet-draft.
