	Adrenaline Created to build a very fast, reliable operating system core. Small, student-developed OS, based on MIT Exokernel. Goals: speed, reliability. In early development. A GUI will be added later. [Open Source, GPL]

	dr'ex Kernel with architecture like exokernel but varies from such where simplicity can be had, coded in C/Assembly. Early development. [Open Source, GPL]

	dr'ex: SourceForge Information, news, forum, CVS, downloads. [Open Source, GPL]

	Elysium Main idea: enforce no abstractions, rather, have them as options, to all levels of system: hardware, kernel and file services, ways users interact with system; based on exo principles. Descriptions, news. [Open Source]

Exokernel: An Operating System Architecture for Application-Level Resource Management
Traditional OSs limit application performance, flexibility, functionality by fixing interfaces and implementations of OS abstractions such as interprocess communication and virtual memory. Exokernel address this via application-level management of physical resources. [ResearchIndex] You Would also find info related to Dawson R. Engler, M.

	MIT Exokernel OS Puts applications in control, runs 10x or more faster. Exopc and XOK versions run on x86 PCs. ExOS library gives user-level extensible implementation of Unix OS, so most applications compile and run with no change. Download. [Open Source, MIT]

	TUNES Project: No-Kernel Unique description of operating systems without kernels, links.

	Unununium Operating Engine Claimed as radical new approach to OSs: no-kernel, self-modifying cells (like objects); single address space, useful where memory and CPU power is low, and maybe for AI. Written in self-modifying, modular assembly language. [Open Source, BSD]
