Because you asked:

That was tangled up in a discussion of generating cookies on the NTS-KE server 
in parallel with generating them on the NTP server.  In the normal case, there 
is only one cookie format wired into both.  The way to make the which-format 
question interesting would be to change the format on the fly, so I described 
a way to do that.

That's not a detailed spec, just an outline.  We might decided to change the 
size of a field.  Not likely, but worth thinking about.
