answer:I don’t think so, otherwise you could be sure it’d be hyped up to death on Digg.com . Just look at the hype surrounding Compiz Fusion, then combine that with the hype surrounding anything Apple… And in any case, I doubt something that expansive (especially considering CF’s plugin architecture) could be written in a non-open source fashion – and in the end, open source works best on Linux. You could hope for someone someday porting it to OS X, but then again, that’d require X.org or whatever and in general would be a lot of work I think, and not as stable as CF (which already isn’t the stablest software).
