Yes, I type in Dutch, English and sometimes German. You have to check if the distance advantage also goes for the three languages, for me they all are more efficient and more comfortable in Dvorak with the I and U reversed. It's not that much more comfortable, but definitely noticeable. When you have had RSI anything that makes typing more comfortable helps. Of course if you want the most efficient (you first have to decide on the factors, and the most efficient combination) layout for each language of the most efficient for the average of each language you can have a nice hobby for a year. I was afraid I'd end up with an esoteric layout and then after a few years find out that there was a better layout and I would learn that one all over again. Instead I decided to stick with DVORAK with an improvement tweak so it would be also more or less be usable on Android en iOS.
