[FidoNet]
1. What the Opus BBS software and sysops call FidoNet.
2. Fanciful term for a cyberspace expected to emerge from current networking experiments (see the network). The name of the rather good 1999 cypherpunk movie The Matrix played on this sense, which however had been established for years before.
3. The totality of present-day computer networks (popularized in this sense by John Quarterman; rare outside academic literature).
