As Promised some documentation, http://blog.buttermountain.co.uk/2006/11/06/accessing-persistent-objects-with-apache-ws-xmlrpc-30-a-documented-example/
As I figured out how to get a simple persistent object into my handler classes I decided that I would create a very simple example to demonstrate how it can be done. I've created a document to accompany the example, its included in the code zip file (linked to within that post) and its pretty much the content of that blog post. The document is aimed at people who are not familiar with ws-xmlrpc 3.0 and I hope it helps bring together the various FAQ entries on the site into one example that people can use as a reference. I'm sorry that the code formatting in the post is non-existent but wordpress is not something I use often. Any corrections, suggestions etc please send them my way.
