You are right Carlisle - they were marginalized. But the reason that anyone 
possibly could marginalize what I was saying was 
'cause they refused to state how the Protocol was to 
be used. What you and the rest of the Authors did was 
to create a protocol for verifying signatures in time 
and declared that the be "the Time Stamping protocol" 
and that is just plain wrong.

What you should have done is said "we are creating a 
protocol to memorialize events in time and to make them
comparable to each other thus." And then with that 
simple statem a set of uses could have been nuilt for 
the tokens and their creation. Instead what you have 
done is built the plumbing for the movement of the 
time without qualifying the time so that the content 
is essentially anonymous in nature.

If any of you authors had built a real word use model 
for this boat-anchor you would have come to the 
conslusions I and the other auditors, pki designers, 
time keepers, and security specialists who looked at 
the protocol did. And that is that the protocol is of 
limited if any real-world use since already existing 
methods do the same things and are already legally 
accepted by Courts on a global basis.

Thus the TSP and its TST's are an overhead not a blessing 
of testimonial value.
