The terms "client" and "server" are common in discussions of CORBA, yes. Strictly speaking what you've really got for any given local/remote method invocation in a CORBA distributed system is an object that receives the request, and a caller (client) that invokes the method on the receiving implementation entity - the real server is an Object Request Broker (ORB). Myself when doing CORBA I prefer to refer to things as client, servant, ORB etc, and not use the term "server". YMMV.
