This is awesome, thank you! Yes I think there are a couple of minor corrections to make but I haven't had the time to go do the research yet, so hadn't yet responded. Nothing is "supported" upstream anyway until there's a system with a DTS that uses it, and that won't happen until after the end of the merge window. Again, thank you very much, it's a safe thing to take for now. -Alex
