But CIAO supports the CIDL, which is *not* present in the lwCCM
specifications.. Isn't it?
I also believe that it supports other features not stricly present in
the lwCCM (segmentation maybe? I don't know it well, so I can't say

Anyway an off-topic question is also what's then the CIF for lwCCM, I
mean how a component executor implementation should look like if,
following the specs:

"The Component Implementation Framework (CIF) defines the programming
model for constructing component implementations. Implementations of
components and component homes are described in CIDL".

But the CIDL is not part of the lwCCM profile...

Yes I understand.. In fact I had no luck in finding anything suitable.

Yes it helped, but as you might have seen I have still confusion in
drawing a circle around what is exactly lwCCM (and nothing more), and
if it can be supported in C or implemented in C on top of an existing
Corba ORB without a lot of pain (->no mapping specifactions, etc..)
