The JNFS system demonstrates the viability of a Java-based network file system. Although JNFS cannot complete with a native NFS implementation for performance, it fills a niche left by the omission of a network file system in the Network Computer Reference Profile.
The strength of JNFS lies in a more secure challenge-response protocol for authentication and interoperability with native file systems. Both low- and upper-end NC users can benefit from these capabilities: low-end NCs gain support for a network file system and upper-end NCs gain support for network file systems other than NFS.
