This posted to Blogger Developers Wiki just about sums it up for me:
"I feel I've got the experience to say that SOAP is gross overkill for this application. It's far too complicated, and the number of arguments about various technical aspects of it above on this page is supporting evidence for that statement. I used SOAP for a couple of different projects, and both interfaces were eventually discarded for simpler methods. In one case, going to XML-RPC made life much easier and still provided every necessary and nice-to-have feature, without the fragile, inefficiences of SOAP."
Keep It Simple...
