I know nothing about CORBA, but I agree with you that the higher success 
of protocols over APIs is a coupling issue, and in fact I'd go further 
and say it's nothing to do with sync/async. For me, the simple problem 
is that an API gives closer coupling between content and transport, 
whereas a protocol give looser coupling. Message structures change 
independently from transport details, so why link them? That's why I 
push document-oriented messaging for business web services.

Francis.
