Not even that, you'd just use it to seed AES-CTR and use that for the
initialisation.  Generator bit-rates seem to be like Javascript engine speeds,
a mostly pointless [0] figure that's provided so you can show that you've
managed to crank your numbers higher than everyone else's, like Benzino
Napaloni and Adenoid Hynkel cranking up their barber chairs.

[0] I'm hedging my bets here with "mostly", in practice I think it's closer to
    "entirely pointless".
