Last time I checked , each sat was divisible (internally within Lightning) to 3 decimal places. I'm thinking one day maybe our Lightning wallets go out to 8 places within the sat, much like Bitcoin L1 wallets go out to 8 places to get us to 100 million sats. Do we go that far?

Yes we can already divide a sat into 1000 pieces on lightning. As time goes on we'll use smaller amounts to pay for the same stuff.
