Sorry I think it was me who misunderstood :-) Anyway in the new
command-line API I would be more inclined to have limits defined using
"-object throttle-group" and -drive would only reference the group id.

I understand that this implies that it wouldn't be possible to create
anonymous groups (at least not from the command line), is that a
problem?
