binary results from beanshell?

I think this is a good idea and a lot of people could
benefit--including JDEE folks.

I'm working out a plugable architecture for subordinate process
command-event-loop Java programs like beanshell, jython etc.  There's
a common lisp implementation I've thought might work as a better
supported replacement for the dying (dead, really) beanshell project.

That implementation is:

Not really, at least in the current form of the way beanshell is used.
There are often issues with quoting and no real way to read data back
and forth in this way.  The data mechanism on a return request from
beanshell to Emacs is emacs lisp or the raw results returned and used,
usually to print on the screen.

Yes, if you bind it to the global namespace or "child" of the global
namespace.
