Local node resources are not necessarily available to netlets. Services that provide disk, network, and other resources local to a node may be accessed through the normal language APIs through a trampoline mechanism, allowing code written against the normal language APIs for disk I/O and networking to be re-used. The trampoline mechanism is used to make any compatible service available through the normal APIs and does not imply that the resources are being supplied through the local node. The API supports trampolining to the extent made possible by the language.
Basic networking facilities must be available to all netlets, and are billed according to the netlet's contract with the operator of the node.
