Several years ago, I wrote some software that used S-plus as its
back-end and Java for the front-end. I found what worked best was
to add a pseudoterminal inbetween; you can use the code from
"UNIX Programming Environment" to create one. The solution was
later reused when a similar project used R for its back-end.
