Subject Re: Questions about CORBA

There is an option 3, which we did not pursue because of time 
constraints, fix and use OpenORB.

Rick, I'm glad to hear that you're working on making our interop code 
more portable.  It's hard work and it definitely needs to be done.  I'm 
also glad to see that you're discussing your ideas w/ the community; you 
are an example for us all.

I am happy to help out where I can.  Can you file a Jira issue so that 
people know that you're cleaning up that part of the universe?
