I doubt that, because:

* All the devices (at least those I've seen somewhere) that follow
semantics similar to IEC61158, are actually IEC61158. (maybe not
everybody fully spec compatible or some dialects). Because that's
exactly the industry standard for anything that works on that shared
process memory model.
* the other fieldbus'es I've mentioned have completely different
semantics and just fit in here.

Therefore: we should call things exactly what they are. We don't call
grapefruits apples, even though both are round and tend to contain a
lot of sugar.

I don't like the idea of name changing *after* this went to mainline
and people are actually using it. At that point, people might even
already written their own drivers, so they'd have to change them, too.

Please let's do that ASAP. It doesn't cost us much at this stage.

@Greg: is that already in your tree ? What do you think about doing
the name change now ?

If your patches haven't been taken by in Grek yet, it IMHO would be good
to rework the queue w/ the missing pieces (-> v12). Otherwise separate
patches ontop of the already applied queue probably would be better.
