[1] one man's data is another man's commands, for starters.  All networking

postscript to printer, etc.

.. and all of that is just data to the kernel.

Yes, vt100 escape sequences etc _are_ commands, and boy have we had
bugs in that area. But there the excuse is "that's how the world is".

... along with "something similar to ncurses-based programs usable over
ssh is a good thing to have, without having said ssh somehow intercept
and marshal ioctls" ;-)  I can just imagine something e.g. RDMA people
would've designed instead... OTOH, I'm eating right now, so better
not go there...
