This whole thing about SCA cracks me up.

Here they say it's the answer:

Then they admit that that CORBA is a loser for this application.  No kidding.

Reading between the lines, this looks like they're going to throw out
the SCA spec (the whole thing is based on CORBA/IDL), do something
else, then call the new thing SCA.

Note that anyone with half a clue who read the spec when it came out a
couple of years ago could have told them that it wasn't going to fly.
I wonder how many billions of tax dollars have been poured down this
rat hole so far?

I understand that they're trying to solve a problem, but OMG/CORBA/IDL
isn't the answer.
