Soft-node
From Friend2Friend Wiki
Soft-nodes provide the soft environment for processing threads. Each F2F Soft-system is made up of a tree of these nodes, which are instances of a module. Each soft-node may have a set of other soft-nodes as its children, each of which must have a unique NCName to identify it.
This result in each soft-node in the system having a unique id, which is its path, and corresponds to its own folder in the directory structure which implements the soft-system. This folder is the root of the file system accessible to the fs-internal-* core services.
