Screenreaders for Mac Drying Up?

Maccessibility has an interesting piece about the last vendor of screenreading software for the Mac giving up the ghost. This appears to be a legacy of the huge shift from OS 9 to OS X, which shook up the market for Mac software across the board. Hopefully someone will pick up the banner on this one — accessibility is too important to be left unserved (especially on a platform as theoretically user-focused as the Mac).
