First of all, thank you very much for your answers.

Well, EDMA is mainly the same as COM, a system for packing classes as
components and link dynamically their in the applications. In this sense
the system is related to the same process in the same machine.

What I had added is an extension system that I call SIU. This systems
allows the programmer to create classes that subtitute the EDMA primitives
(create and destroy objects, property acces and method invocation). So, you
can write code to send this primitives to other process or machines (I had
a simple system for remote object interaction). I had another SIU extension
(in development) for using Java classes within EDMA as their was EDMA classes.

I will like to use CORBA as distributed system. I think that what I must to
do is an special Object Adapter for manage EDMA implementations. I must use
DII for EDMA-CORBA because all EDMA operations are done at run-time. Is
this the correct way?

I tried OmniORB but DII is not implemented. I tried Mico too, but I can
compile it in my Linux box.

I had been talking with rms@gnu.org and he tell me that will be interesting
that EDMA work well with GNOME. I couldn't install GNOME upto the moment
because I can't install Mico on my system (I still know what's the
problem), so I don't know very much about GNOME, and then I don't know the
way that EDMA will work with it.
I think that the way is making EDMA work with CORBA. Any suggestion will be
fine.

I will try to do this. I must to talk with my system administrator.

Thanks for the comment, and thanks for download and take a look at it.

What does this means?. Sorry I understand this phrase.

Thanks for the information, and for your quick response.
