I don't know all the gestures available on the remote so I can't say for sure if there would be some sort of conflict, but from my short test I don't see why standard pinch-to-zoom gestures wouldn't work. Here's hoping they add this feature soon. I don't have the best vision so pinch-to-zoom is quite important to me.
OK folks, we have seen some great stuff with this new bridge update. Now let see what the new OS 2.0 will bring. Maybe some of the options we are looking for are on the new OS update...
