stunnel is the tired version of inter-machines communication. It's a basic, raw socket between two processes, and all layers above must be reinvented again and again. Plan 9 with its protocol 9p is the wired version of inter-machines communication. You don't just link two random processes, you have the possibility to interconnect two directory trees, and since most useful software works through a directory tree, this means two processes can be linked by importing another tree on another machine and doing everything locally. It's possible to write something like "echo UNSEEN | imap-search | imap-get-summary" and have actual IMAP stuff done on another machine, and you don't see any of it. It is also possible to use `rcpu` to do what ssh does, and even more: the remote machine has access to the local machine. So for instance you can edit files locally, and have a rcpu connection to run builds on another machine that picks it from your local workstation. No clunky sshfs, no failing NFS, ...
