I don't read it as a discussion of what is "proper," it's more a
clarification that there are situations in which the asynch/postal model is
more appopriate than the synchronous/RPC model.  The "RPC" model is more
widely understood, but an alternative "camp" that develops visions and tools
for the "asynch" model is starting to coalesce.

I've also noticed this trend, but prefer different terminology, the "strong"
and "loose" camps:  one tending toward tightly coupled architectures,
development using strongly typed languges, and a synchronous (RPC)
communications model; the other tending toward loosely coupled
architectures, untyped script languges, and an asynchronous communications
model.  [We definitely need help on the terminology, so suggestions are

I hope that Curt elaborates on his perspective, but some of the people and
technologies I see that that support the "loose" camp would include
McGrath's XPipe
http://xpipe.sourceforge.net/Articles/Documentation/fog0000000039.html, the
RogueWave Ruple http://www.roguewave.com/developer/tac/ruple/ product, and
JXTA-spaces http://jxtaspaces.jxta.org/ "XML spaces" efforts.   Also permit
me to mention my employer's EntireX Orchestrator product
http://www.softwareagusa.com/products/entirex/orchestrator.htm as an "asych
toolkit" that may support the "loose" paradigm.
