If I recall correctly (and it's been a while...) csup, CVSup, et al were based on `sup`, which was a file distribution tool somewhat like `rdist`, which came from CMU. csup/cvsup was optimized for moving source code deltas (a la CVS repositories) around. I recall a graphical client written in Modula-3? The SUPDUP protocol used by ITS hosts was a "Display Protocol" based on TELNET: https://www.rfc-editor.org/rfc/rfc734 I think the similarity in naming was just a coincidence. - Dan C.
