It is my suspicion that seeds which depend on machine states(ie state of your computer at a specific instance of time) would always be subject to scrutiny and de-cryption. As long as the software used to encrypt is not self-modifying, the machine state can (through careful manipulation involving temperature, clocks, processes etc)always be replicated and fixed to an acceptable degree.

Try getting a human to type with the same timing, to microsecond precision, the same way twice.

That assumes that you have someway of measuring the timing to microsecond precision. On most machines I've been on, if you get something time- stamped, even if there is a microsecond portion of the timestamp it's meaningless because it wasn't based on a timer with the required precision. If a timer can only resolve milliseconds, the microseconds don't have any meaning.
