Uh... CSP communication occurs by synchronising events between (possibly unnamed) processes. Each process offers events, and some events are only permitted to occur when every process in a synchronisation group offers them. Channels (which are a concept going back to CSP) are essentially families of events (so the set of events in.x for any x would also be referred to as the channel in). The main difference between CSP and the languages that are sort of based on it (and this is a difference that predates Go by a long time -- it's visible in occam, for example) is that CSP events aren't directional or procedural like channels, they're just things that sort of happen (so they don't have to be written from one place and read in another -- they can occur with only one process running, or can be used to synchronise between more than two processes, or one process can restrict another by not offering events). Communicating through named processes would be closer to the actor model than to CSP.
