Const (Insecure Sensory) Keys

Actually, I think both kinds of sensory keys could, at least conceptually,
be seen as simply part of the "standard" object protocol that all
kernel-implemented objects, and some user objects, may implement.
Bryan has identified a feature that appears to be missing in KeyKOS
that I think is worth considering. He has essentially invented a
"const" key - a weakened form of sensory key that does not violate
encapsulation. "const" is a key attribute, and the invocation of a
const key is made visible to domains by some bit in the message
This strikes me as highly parallel to the C++ notion of const, which
is empirically very useful.
I'ld appreciate reactions from the KeyKOS crowd.
