complete OS-independent data transfer API that abstracts system specific code and provides mechanisms for complete control of bandwidth usage by the application code.</P> +<P>NeL Net has a further objective of providing a complete toolkit, comprising further layers of library code and core service implementations, for the development of performance critical distributed program systems for massively multi user universe servers. </P> + +<H2>Features</H2> +<H3>General Features</H3> +<UL> +<li>A layer based architecture with API access to every layer +<LI>Client application API
