Yes. Many applications could use a better IDL definition. Part of the
motivation for building Mono, was that it was very hard to design nice
CORBA apis purely from C. It is completely possible, but you required
people to understand way too many things.
What we wanted to do all this time was to allow people to focus more on
the problem they were solving (in this case DIA) instead of having to
learn everything about corba, interfaces, wrapping, object activation,
processing patterns and so on. And C# and .NET seemed to fit that
description really well.

IDL is a generic term that is sometimes confused. I liked what you
originally used: `OMG IDL', because it refers to the CORBA version of

Do you have a particular question about the interfaces?

Depending on your task at hand, you might want to look at different
approaches. Out-of-band data has been used for a long time in RPC
systems (Mach's Interface Generator made this explicit in the interface,
other systems have to implement their own hacks for transport).
For instance, you can use the interface to exchange a shared memory
handle and pass information there.
