>One of the examples from the Plan 9 survey paper is the way FTP access to remote sites is implemented. There is no ftp(1) command under Plan 9. Instead there is an ftpfs fileserver, and each FTP connection looks like a file system mount. ftpfs automatically translates open, read, and write commands on files and directories under the mount point into FTP protocol transactions. Thus, all ordinary file-handling tools such as ls(1), mv(1) and cp(1) simply work, both underneath the FTP mount point and across the boundaries with the rest of the user's view of the namespace. The only difference the user (or his scripts and programs) will notice is retrieval speed.
