Going through COM would definitely be a bad idea. The way to do it
would be to write C wrappers around the bits of omniORB required, then
interface to the C from C#.

There would be two ways to do it. One would be to work at the same
kind of level as omniORBpy, and write your own marshalling code in C#
(plus C interfaces to the omniORB C++). The alternative would be to
generate normal C++ stubs and skeletons for the IDL, then wrap those
from C#. In either scheme, you would also need to wrap object
references and servants so they could be shared by C++ and C#.
