Also, working with a MMU and other memory protections, is fiercely desirable, a lesson I painfully relearned a few years later with a ucLinux based IP PBX... I also need to straighten out the historical record some, as so many have contacted me over the years with their personal stories, and in particular a fellah by the name of Elmer Joandi (based in Europe) was arguably the first to make the concept work, beating us by at least 6 months. Dozens of others hit the mark within weeks of each other. Stuart Chesire has shared his stories privately with me about Apple's AirPort adventures (and creation myths) that I guess he cannot tell before he retires. :( (between us we won the above patent case but for all I know there was more - the court records are sealed) I am happy our teams have fixed at least some of the problems introduced by wifi4 and wifi5[1] and wish they were deploying faster - especially into the cafes that I love to work out of so much - as well as I wish we could tidy up more than a few left over problems from the make-wifi-fast effort... But I hope wifi7 and later are going to be someone else's problem. ... I still remember vividly, sitting on my rooftop, that December, 1998, in the rain, wondering where the wifi technology would go.
