First, I'm CCing the jCIFS mailing list. That's currently where
idlc/jarapac is discussed. I recommend getting on that list if you want to
follow the latest idlc developments. It might be useful if really end up
using idlc/jarapac.

Yes. But I recently changed the Java emitter quite dramatically (see
idlc-0.4.0) so I need a chance to play around with that first to verify
that the technique is going in the right direction as it will surely
influence the C emitter.

Also I'm only willing to do a skeleton that does the simple stuff. You'll
have to flesh it out and get all the test cases working. It's only about
~500 lines of code but you have to know NDR very very well to get all the
test cases right. Is that ok with you?

This doesn't sound like a really great idea to me. You really want to
throw Java into the mix, write a Java server stub emitter for idlc, and
duplicate all good chunk of DCE glue just for the port mapper? Again,
Jarapac is just client side right now.

It's eric.glassATgm ail.com.
