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