If the MTBF for a remailer is n then the MTBF for m remailers
is n*m. Inother words the remailer chain gets less reliable as
it gets longer.
Jim, you want to take a look at that "n*m" again ... it
doesn't wash. means MTBF goes *up* which means *more* reliable.
Remember n is a fraction, failures/time_period ...
If your MTBF is 1 failure per year for each system and you have 10
systems your MTBF is 10 failures per year. Looks like multiplication
to me....
Maybe I have been away from hardcore engineering for too long, but
last time I checked MTBF (Mean Time Between Failures) is measured in
time (seconds, minutes, hours etc) not in failures per year that would
be called 'failure rate'
