We are going by the International Telecommunications Union definition of "real-time" of being less than 1 second latency. See ITU-T Rec. F.700, "Multimedia Conversational Services", section 2.1.2.1 So, according to ITU-T, instant messaging is NOT real-time -- required for true "CONVERSATIONAL" interactivity. ....Deaf people used to use TTY a lot more before. (sometimes called TDD or text telephones -- often used in conjunction with voice, or without, depending on deaf individual). Fewer deaf people use TTY now, due to the widespread availability of cell phones and Internet. ....Some (not all) deaf people, like me, have regressed to being forced to do line-by-line messaging because real-time text is not as common on the Internet as it was during the TTY days / BBS days / Unix Talk days / terminal days. Introducing XEP-0301 provides the true real-time (1-second latency) capabilities back to my every-day communications, including future telephone relay services (Wikipedia: "Telecommunications Relay Services") -- whether I am calling Pizza Hut, or contacting 9-1-1, or calling your home phone, since the operator reads out what I am typing. ....Some of the Internet based relay services (Google: "IP Relay") are using proprietary real-time text standards, and I'd rather them use XEP-0301, so that we can create/use the software we can all choose, whether laptops or cellphones. ....Likewise, we'd also like to be able to message directly to people, if the other party has an XEP-0301 compatible client, too, and if they have it enabled. So we have a big interest in keeping chat software "Accessible" (and are also modifying other accessibility legislation too -- some of our group have met with U.S. government officials, etc) -- because we need modern real-time (as defined by ITU-T F.700) methods of communications -- some of us are not using as much as before.
