Can the node and domain keys still be effectively "emulated"
(substituted) by an extension (e.g. remote) key? If the kernel
knows node and domain keys when it sees them, that would
seem to suggest that it would know when it received an
extension (e.g. emulating a node or domain key) key
instead. In my limited experience (e.g. with RATS) that's
an area where care needs to be taken to insure that all
the base system capabilities can be emulated/extended
(as the file capability was not on RATS).
Just thought I'd ask. Perhaps Charlie knows?
