OK, I agree.

Well, though the _use_ of such devices might not be "industrial",
_technically_ they are very similar to embedded systems found in
automation or other industrial equipment.

Many of these devices (all that have mmappable memory) can be handled
with a UIO driver, but for the rest (mostly stuff connected to serial
busses), it's important to have a subsystem in the kernel. I really
don't care too much about its name. BTW, before UIO was first published,
its internal name was "Industrial I/O" ;-)

Thanks,
Hans
