Now I think that you talk more or less about something which =20 could be implemented e.g., as an userland library which not only polls =20 the kernel sensors framework, but provides the single-system sensor =20 data (and could be a base of a singe-system sensor daemon which feeds =20 its data to a group-level sensors framework). Does this sound like =20 what you have in mind?
