NetKernel is an open-source Internet Operating System from 1060 Research (http://www.1060.org/). It provides an advanced microkernel for executing applications, processes and services and a comprehensive set of modular add-on components.
It supports a unique dependency-based caching architecture which provides dramatic application optimization, and uses XML throughout it’s implementation. NetKernel is free to evaluate. It may also be used at no charge under an obligatory open source model.
