The API support getting data that has 1 bit of entropy per 128 bit
received (DRBG_MINMAX_FACTOR). If it's worse than that, you might
have to write your own extract method.

A stream of bytes it just fine.

I think the tme delta will really depend on your source. If it really
changes all the time, it really doesn't matter much how fast you
do it. But I think some (most?) of the variables don't change that
often.
