This looks awesome. Whether 500 WPM or not, I would give this a try. Long ago I learned the BAT one hand chorded keyboard. For one hand typing, I got to around 50 or 60 wpm - but only prose. It was much too slow for programming, as symbols and modifiers required their own chord plus the chord of the final character. But with two hands, or even some modifier key foot switches or a second chord hand (like the CharaChorder), it should be fine.
