I know it's way too late for design questions, but the thought just
occured to me: -device gives you what you need without defining yet
another command line option (good!), but is it appropriate?  It's not
exactly a device...  Would -object be a better fit?  I honestly don't
know.  Paolo?

If this question leads to changes, they can be done on top.
