Yes, that does not sound bad. It is a common term in the redmond os,
and I think I even saw it in the kde control center last time I used
that.

RAID is in /sys/block/md*/md  ;-)

Naturally, just like it would in procfs.

To a given extent yes, because procfs code is somewhat different
from sysfs is somewhat different from a character-based device.
(Maybe you also want to have both a device and a sysfs file, like md.)

(Mentioning "halfqwerty" reminds me of Sony's 13-key Thumb Phrase "IM".)

What accessibility functions does Windows have that Linux (in
general, things are usually implemented only in X or KDE) does not?
