naive question, but why can't you run the screen reader on the remote instance and wire key presses through? I do something similar when I need to remote desktop without using my hands - I install hunt-and-peck on the target machine, then I can say the hotkeys to bring it up and say letters to click things in the remote windows.
even if you have a crappy screen reader, it's better to throw your disabled users some kind of bone than to make them wait for some perfect solution that will never get properly funded.
