in the mean time i thought the following: CORBA objects should be the
"servlets", they are higher level then the underlying simca_object_t
based ones. they are, i guess, what i used to call components, except
for GUI part (GUI is postponed to better times). 

i think on CORBA level we will need another interface - Link. it will
represent either simple out->in connection between objects or the
intelligent connection to remote object. in the second case Link object
will hide actual network streaming mechanizm and in any case havig such
an object will allow uniform representation of any connection - local or
remote. 

i'm still doubting if the simca_object_t and friends should know about
CORBA or not. i prefer them to not bother, but i don't know yet if
that's possible.

BTW, i've commited first .idl files to cvs, they may be oversimplified
at the moment but at least we can start experimenting with this
approach.
