Nope. That's been one of the plot bunnies I've been fighting for two years, before they'd even aired the pilot, because...well, it sounded like the prequel to Firefly. And honestly there's not anything you'd actually have to skirt around, because Firefly is 500 years later and, as we all know, history is written by the winners. Any "discrepancies" in the two plots could be (and actually make the most sense as being) something hidden by the higher ups, or just lost in the move from Earth or through time.

Even the loss and change of the technology in the two makes sense if you look at it from the standpoint of "Well, we know they did this, but they destroyed any trace of how, so lets figure it out for ourselves"

Yeah. I've put no thought into this. At all. Ever.
