The SWG has agreed to take it on. I think it is appropriate for the 
SWG to work on this.

Ok. I assume that your 1 byte of version information is broken into 2 
4-bit pieces, one for the protocol version and one for the IP version.

What about making the src and dst ip fields variable length based on 
the IP version (4 bytes for IPv4 and 16 bytes for IPv6). 

That would provide more private data for IPv4 networks at the expense 
of a variable sized header and all the complexity it entails.
