I for one, would be really interested in any moves to make Hurd use

I think (from what I have seen on the linux-kernel development mailing
list) that the power of CORBA is that you can use any communications
protocol, not just IIOP.
So, while IIOP might be the best for inter-computer communication,
something else might be more optimal for interprocess communication.
However, IIOP probably is a good starting point.

Multi-language support might already be possible with MIG(?), but

I am not really familiar with these issues, but I think it would still
be worth it even if it led to short term breakage and/or
If you haven't done so already, I would recommend you look at the
ORBit implementation of CORBA. It aims to be a small, efficient,
implementation that has been ported to the Linux kernel (some people
were pushing for CORBA to be used instead of the conventional /proc/
text mode files).
