Why do we have that stupid "hose" name? Only because of strange alpha
naming, or did somebody else also use that incredibly silly name?

Please talk about "domains", at least it makes some sense as a name.

I agree.

I'm also hoping that /proc/bus will eventually go away, so I don't
see a major problem with not understanding multiple domains at that

On a /sys/bus/xxx level we actually should already be able to handle
multiple domains, but the naming is broken. However, in /sys we should be
able to nicely handling non-zero domains by just extending the name space
a bit.

My only concern is what file lookup algorithm we should be encouraging
things like xfree86 to use. Check /sys then /proc/bus?
