Umm.

Guys, if your argument is that you cannot possibly distinguish the
Intel implementation from "true" randomness, then WHAT THE HELL are
you complaining about?

We don't even care. "True randomness" and "something we cannot
possibly even test and distinguish from true randomess" are 100%
equivalent. Stop with the idiotic "we cannot test it" crap. If it
really is indistinguishable from true randomness, nobody will ever
care.

It's that simple. Really.

And if somebody ever figures out that Intel flubbed, and you actually
*can* tell it from true randomness, even then, what's the downside? It
will be practically random anyway, and we'll be mixing it up some
more.

Seriously. This whole discussion just makes me convinced that security
people are so far removed from reality that it's not even relevant any
more.
