Please see this old TUHS post for some more background in DMR=E2=80=99s = own words: https://www.tuhs.org/pipermail/tuhs/2019-August/018325.html On the topic of DMR Streams, I=E2=80=99m increasingly intrigued by its = design: recently I=E2=80=99ve been deep diving into classic USB to = better understand this class of devices and how to drive them = (https://gitlab.com/pnru/usb_host). It would seem to me that Streams = would have been a neat way to organise the USB driver stack in a v8 = context. Note that an USB analog did exist in 1982: = https://en.wikipedia.org/wiki/Hex-Bus Sometimes I wonder what combining v8 streams with v8 virtual directories = (i.e. like Killian=E2=80=99s /proc) could have looked like. Having the = streams network stack (or usb stack) exposed as virtual directories = would have been quite powerful.
