The problem isn't the lack of implementations (I'm already using Brian Gladman's very nice implementation), it's that -384 and -512 are horribly inefficient on the majority of systems. Even -256 is painful on register- starved x86 (so we're talking 95% of the planet here), but it's the most reasonable tradeoff of the lot. So I'd support -256 SHOULD, -384 and -512 MAY. Peter.
