I wonder how much DBus (the Inter-Process-Communication (IPC) standard Linux desktops have been based around) is baked into QNX & instrumental to it! Maybe I can find out now?

That was such a time. It's sad that it was a security panic, to me, because there was incredible promise there... All of the cars infotainment, windows, interior lighting, HVAC, all these things are just DBus services hosted on QNX? And I can just connect to my car & modify them, in some cases even over the air? QNX & DBus could have been a huge selling point, could have been such an awesome way to debundle the car from its infotainment. If only.

Really interested to see if DBus really does underpin much of QNX, or whether this was just a time & place. Seeing how monolithic versus networked QNX is in general would be fascinating; is there one or two QNX hosts & lots of devices, or so the story more distributed that that?
