Also they have varying levels of impact on your system. pipes/stdin/out are extremely low cost to implement. CORBA - expensive. DDE/COM non scalable." And since one of the newsgroups being cross-posted here is comp.lang.ada, we should add (as another low cost option), the RPC interface provided by the distributed systems annex of the Ada RM, which has been successfully used for both homogenous and hetergenous distrbution, on single machines, and on networks.
