In general, that makes sense.  I'm not quite sure yet the relationnship
between coupling and typing.  For example, is corba's typing more or less
coupled than html web or web services?  And I don't get the "data validation
as part of service".  How does that compare the html web vs xml web services
vs corba vs dcom vs smtp vs ?

I'm not sure about that, but I think it ties into the trade-off between
loose coupling, typing and robustness.  Which starts us down the "are
compiled applications more or less loosely coupled than interpreted
applications" path that I don't actually want to go down.
