angry tapir writes "Researchers at the PlanetLab global research network have developed a potential replacement for the widely used Unix sudo tool, called Vsys, that will offer administrators far greater control over what end users can and can't access. Vsys is similar to sudo, except it offers finer-grained access to system resources. PlanetLab created Vsys as a way to allow its researchers to access low-level network functionality so they could develop new network technologies — overlay networks, user-level file systems, virtual switches — while their experimental work remained safely isolated from other users."
