I work remotely as well, but at our company we do a lot of screen sharing meetings. I wonder if someone should build some sort of VNC (or zoom, or adobe connect) that plays well with screen readers and doesn't just send a video feed. Or maybe it already exists.

I myself have macular degeneration, which while not disabling right now, has started a bit too early in my life. One day I might be almost blind myself and I will definitely need this.
