And why wouldn't this work today? Imagine getting an awesome piece of kit like your PS3/4 and being able to code on it, run anyone's code on it. Hack it to your heart's content. I reckon that would (a) rock. (b) foster an amazing community. The things that made the Amiga rock could make any specialist piece of hardware rock, what's prevents it is that companies like Sony and Microsoft are anal control freaks.
