I have decided to do a project on operating system design for my science fair project at school. I have been doing some research, and am trying to find some concept that hasn't been exstensively tested or explored. Most of the information that I read is about established operating system design practices, and I am having trouble finding information about cutting edge ideas that have yet to be fully explored. Does anyone have any suggestions on possible ideas or good sources of information? Thanks.

Exokernels seem to be an active area of OS research right now.

Exokernel seems to be the most fashionable research area right now (A simple google should turn up plenty of links).

Another fun idea to explore might be a massively distributed operating system, where every computer in the system just represents more resources for the whole system (That would be an extension of grid computing to general use).

Thanks, for your help. I will look into these ideas.
