Just getting a bit off-topic here -- I can understand that for  
backwards compatibility this is totally the way to go here, but are  
new fonts being implemented with AAT tables at all now? And if so, is  
it just because Mac OS X doesn't support OpenType well enough? Or are  
there still relevant areas of AAT that are superior to OpenType?
