The next version of Janos includes package-level access controls on
each flow.   In ANTSR we limit dl'd code to its own package and the
ANTSR core package.  Locally-loaded code is a bit more privileged.
However, we haven't attempted breaking the Node interfaces up like you 
did for SANTS.  Though, I think that should be easy enough to fit in.

I think this method (from both SANTS and ANTSR) of controlling access
via the type system is the way to go.

Once we get this next release out, I'll be very interested in what you 
guys think of it, and if it meets your needs.
