Hi Fabio, I have already finished re-factoring the whole xmlrpc backend.
A new combo list is added to the "new connection" wizard to provide two choices (xmlrpc and rest), as shown in http://dl.dropbox.com/u/3466762/xwiki/newConnectionWizard.png. When user selects "xmlrpc", the xmlrpc implementation is used. The navigation panel can show the xwiki resources, as shown in http://dl.dropbox.com/u/3466762/xwiki/xmlrpcBackend.png. I will continue working on the rest backend following the previous discussion.
