What is Macfusion's network file systems based on?
SSHFS In computing, SSHFS (SSH Filesystem) is a filesystem client to mount and interact with directories and files located on a remote server or workstation over a normal ssh connection. The client interacts with the remote file system via the SSH File Transfer Protocol (SFTP), a network protocol providing file access, file transfer, and file management functionality over any reliable data stream that was designed as an extension of the Secure Shell protocol (SSH) version 2.0.
Cocoa text system The Cocoa text system is the linked network of classes, protocols, interfaces and objects that provide typography and text field editing capabilities to Cocoa applications on macOS. It is the primary text-handling system in macOS. Although "extremely complex", the standard text-handling abilities of the Cocoa text system have been widely praised as without peer. GNUSTEP implements a similar, broadly-compatible system.
