Sorry, I have to intervene here: CORBA does not deserve such a bad
reputation.  It *is* language independent which naturally introduces
some level of complexity.  But, for example, IIOP is pretty well done
since it especially allows for small message sizes - much smaller than
what is needed for a WebService SOAP request and response.  For WAN
communication this is an advantage.

Well, to be fair it was written against a different set of
requirements.  Especially the fact that no support for different
programming languages was needed made things significantly easier.
Plus, of course, the elegance of Ruby helped a lot in making DRb easy
to use and blend seamlessly with local functionality.

I'd *love* to see a picture of that toaster. :-)

Basically the central question for distributed applications is: which
data is stored where and what do I need to transfer between processes.
 Since remote method calls are much more expensive than in process
method calls people typically focus on reducing the number or
frequency of remote calls at the expense of more data being sent with
a single invocation.

Kind regards
