The Simple Object Update Protocol (SOUP) specifies an content-transfer model for digital "appliances" like cameras, printers, scanners, picture frames, personal digital assistants, cell phones, machine control systems, and so on. SOUP standardizes simple but important communications between content-rich devices. It uses Simple Object Access Protocol (SOAP) messages to push content from one device into another. The approach resembles the way web browsers pull content from web servers. More at http://www.hpl.hp.com/personal/John_Barton/HTTP-A/SOUP.htm
SOUP (Simple Offline Usenet Protocol) is a standard, similar to QWK, for reading and posting to Usenet using an offline reader. It never attained much popularity, but it provided a convenient method of Usenet access during the brief period of the 1980s when it was easy to get a dial-up shell account on a college workstation, but difficult to use or configure SLIP or PPP.
