Perhaps.  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.
