They should be made to read the Debian ssh security report - three times
and understand the same would apply to them if something did cause their
network packet arrivals to be observed or non-random

Far better would be to get your CPU guys to put an RNG back into the
systems or on the CPU die ala VIA. Given I've even seen people using VIA
boxes as a random number feeder (streaming random numbers over SSL) there
is clearly a demand 8)
