Is there any support for mounting a remote NFS drive, or mounting a BeOS drive over NFS?

In the meantime, there is an NFS server, BeNFSServer, that was written by Andreas Huber. You can find it in BeWare, or check out his own web site:

Additionally, it is possible to write a BeOS file system plug-in that would mount NFS volumes, just as the BeOS can mount Macintosh hard drives. Be provides documentation regarding how to write file system plug-ins, so a wide variety of foreign file systems, including NFS, will likely be supported in the future.
