I've seen Haiku before and my understanding is that it's a BeOS clone on steroids. Is Google making charitable contributes to open source projects for the sake of fostering open source or do they have some keen interest in Haiku? If it's the latter: I would have thought Google's interests would be served by donating to Linux-based projects.
