We have Xenbus - which is a little bit like OF in that it has data in a hierarchical namespace - and I guess it might be possible to find a mapping onto some generic OF-like interface. However, Xenbus is an active communication channel between virtual machines rather than a static representation of a machine configuration (for example, you can put a watch on a particular path to get a notification of when someone else changes it). But, yes, this is a good KS hallway track subject.
