The ST will be useful if it evolves into STE and can play Pac-Man on E's. Though the 8-bit systems are really where it's at for me! I'd be hyped, even if Amiga support wasn't part of the package! 
The implementation is done by foft, and I have it running here already on the Altera DE1 board.
It's an incredible work! Now, Atari 8bit hardware lives forever, as it's open-source too.
