I can't see why not. Let's do a little thought experiment: Assume we built a device that used a PRNG to generate a DA. Now assume it works. :-) Now assume we made 20 of them. Now assume we started them all at the same time. All 20 would be using the same stream of PRNG values at the same time, right? All 20 would be working fine, right? Now, what would be the difference if we just happened to have one more powerful machine doing all 20 of them? Nothing, right?
