No, and it's probably not a great idea! I do like to get the 'no bad ideas' out though
I meant instead of having 2 devices with 2 decks to avoid the small reloading time, 2 devices could be basically stuck together and shared some component cost, because they don't actually need to run simultaneously.
My understanding is that the final production unit of LeShuffler should be capable of shuffling a full deck in right around one minute. In fact, even if it takes a full 1:10 that would actually still be a tiny bit faster than the 1:20 taken by a Shuffle Tech ST-1000 unit. And even if you are down to 2 or 3 players it should still take over a minute to fully deal and then play out most hands (unless everyone is just folding to the blinds LOL). Thus LeShuffler should be fast enough that a table should never really require two different drums. You will need two different decks of cards, yes. That way you can have one deck being shuffled while the other deck is in play... just like you would do when using any other shuffling device (or even with no shuffling device at all). But you should not ever need two different drums on the LeShuffler unit. But that's just my $0.02 given my understanding of things, obviously @francoisLS is in a much better position to provide a definitive opinion on this.
