Service composition in Lipto

The authors have designed an object-oriented architecture for a family of portable, distributed operating systems. The implementation of an experimental prototype called Lipto is underway. Lipto´s architecture facilities the dynamic composition of distributed services and applications from a set of building blocks or modules. Their approach is based on two fundamental premises. First, a modern operating system should allow applications to dynamically compose higher-level services from a set of building blocks (modules); it should further support the integration of system, third-party, and application provided modules. The second premise reads that a modern operating system must be readily portable across a variety of hardware architectures
