Have a look my short XIOP paper
 <http://xiop.sourceforge.net/doc/xioprationale_1_2.html#ByScale>
for few ideas on the subject, of course within the Corba framework.

IMHO all object interactions should be first class considerations for any
developer,
i.e.. failures in interactions
(inprocess,inter-thread,inter-process,inter-machine)
should be separated from other types of exceptions. In other words I don't
want complete transparency.
