look at it like this:

the simca is a CORBA server that provides interface allowing to
instantiate objects, connect them destroy them, create containers and
move object from one container to another (construct pipelines in other
words).

simca_object_t is visible as CORBA server that allows to assign /
request properties, execute commands etc.

once pipeline is created it functions like it used to (like it does in a
current version), not touching any CORBA things, unless there's a link
to an object far away, in which case something should be different. but
what?

i guess the event handler that is called once object emits something on
a outlet-property should be different. and this handler should be
installed during simca_objects_connect call if the receiver object is
remote. and again this handler shouldn't use corba mechanisms, but
should remain simca-specific. 

i send this to the list for it is worth archiving :)
