Basically, how prevalent are servers out there (both Internet and intranet) with support for Fast Open? http://news.netcraft.com/archives/2013/11/01/november-2013-web-server-survey.html doesn't go down to the OS level, and http://www.netcraft.com/internet-data-mining/ssl-survey/ is only from May and was in the context of SSL sides, but it does provide an interesting break-down of "OS share" which looks reasonably stable going back three years and so probably isn't too far off presently. rick jones
