Just to be completely clear I'm not suggesting the BeOS APIs are insufficient to implement robust screen reader support, just that Windows XP actually did implement it, from the ground up, and integrated it into Win32. I would love it if Cosmoe (and in general, more niche toolkits) would do this, too. It's non-trivial work so it's not like I expect it, but it makes using this toolkit for real programs intended for a general audience much more reasonable.
