Depending on how the PRNG is implemented the "secure seeding" could be
different from what you'd expect, for example using an X9.17-style PRNG you
don't need a secret seed, just a random one, so contacting a seed server that
streams out random (but not necessarily secret) values would be sufficient for
"secure seeding", the seed just takes the place of the X9.17 DT value, the
date/time vector.
