Editor's Picks:
 - Lean, with fast, message-based, synchronous IPC, simply-used external paging mechanisms, security mechanism based on secure domains: tasks, clans, chiefs. Kernels try to implement only a minimal set of abstractions on which OSs can be built flexibly. L3 h
- Orthogonally persistent, capability-based secure SASOS using L4 2nd generation microkernel. Goals: Prove SASOSs can run on normal hardware, be as secure as normal OSs; can be as efficient as, and are faster than, normal OSs in some important uses; can be
- A secure platform for applications that use digital signatures. Based on L4 and Linux. Research project at Applied Data Security Group, Ruhr-University Bochum., Germany.
- L4/MIPS: stable L4 for MIPS R4x00 processor, may be fastest kernel for this architecture. L4/Alpha: begun at Technical University of Dresden, SMP version released. Linux ports: L4/MIPS, L4/Alpha underway.
- A distributed operating system based on the concepts of object replication, component model support and persistence. It consists of a L4 microkernel and a set of distributed objects acting at the user level. [Open source]
- Porting the Hurd to the L4 microkernel. News, plans, pointers to mailing lists and websites.
- L4-based microkernel systems, for embedded systems to huge servers. L4: a tiny, fast, second generation microkernel using hierarchical external pagers and guarded page tables. Goals: create, prove, establish new methodology for systems that helps manage g
- Goal: address the complexity of building and maintaining a variety of custom OSs. As embedded and personal systems grow more common, the need to make OSs customized to many device and application needs rises. At IBM T.J. Watson Research Center.
- L4 and Linux based research project aiming at the support of applications with Quality of Service requirements. At TU Dresden.
- The L4Ka microkernel is an L4 compatible kernel running on many platforms: ARM; MIPS; 68k, PPC; x86. A port of Linux atop an L4Ka microkernel exists.
- Preemptible, realtime, 2nd-generation microkernel, fast, maintainable, readable, supports hard priorities, uses non-blocking synchronization for kernel objects to guarantee priority inheritance, ensure runnable high-priority processes never block waiting
