Proposed Host-Front End Protocol

The reader should be aware of several things in regard to what the present document is up to. First and foremost, IT IS A PROPOSAL FOR A STANDARD, NOT A STANDARD ITSELF. Next, it assumes that the separate document, RFC 928, which is an introduction to the present document, has been read before it is. Next, it should be understood that "final cut" over this version of the document has been exercised by the author of RFC 928, not by the primary author of the present document, so any readers bothered by style considerations should feel free to blame the former, who’s used to it, rather than the latter, who may well be guiltless. (Editing at a distance finally become too hard to manage, so if I’m typing it myself I’m going to fiddle with it myself too, including, but not limited to, sticking my own section on the Conceptual Model in before Joel’s words start, rather than leaving it in the Introduction.
