Tibetan input

i just discovered Christopher Walker's Extended Wylie Tibetan keyboard layout (for os x). i'm impressed, you can do rather sophisticated things with these XML files.

Of course, this is after I spent many hours figuring out how do this using the old Carbon APIs. Enough to know that I don't ever want to have to, and that I'm glad they wrote OpenVanilla.

My disappointment with OV is that it really only does character-by-character input. I want something like the ABC input for simplified Chinese, only it would generalize to any sort of romanized input, like Cantonese. That would be slick.
