Something like that, yes.

Me, nothing. But a guy contacted me to see whether he could use
the java package to make octave available as computation engine
for his Java application: basically, what he would like to do (at first)
is to call "eval_string" from Java, through JNI. The java package
available in octave-forge provides such a function, but it implicitely
assumes that octave is correctly initialized (because the package
is intended to provide a Octave->Java bridge, and not the other way
around; so the "initial" caller is assumed to be octave). For a
correct eval_string behavior, I guess that octave must be initialized.

Thinking about it, what I'm talking about is some kind a in-process
engOpen/engClose/engXXX API.
