The SNTPv4 specification was submitted to the RFC editor in Postel ASCII 
format, but has been caught in the general logjam at the editor's desk 
for over a year. The NTP security document is available only in PDF and 
not in Postel ASCII format and, as it has many equations and unASCIIable 
content, I do not plan to produce an ASCII ripoff.

The recent BOF in Washington kicked off a IETF task force with product a 
definitive NTPv4 specification. The briefings and flowcharts on the NTP 
project page pretty much sum up the algorithmic refinements, but the 
specification itself is some months away. By agreement with my sponsors, 
what leaves my desk will be PDF, not Postel ASCII. I will leave that 
conversion to others.

A detailed explanation and discussion on the algorithms is in a book 
nearing completion. I am happy to have some chapters peer reviewed on an 
individual basis, but pending publication I can't release the whole thing.
