To clarify for people who have been following the discussion, SOAP and XMLRPC in DHTML still need to talk to the LPS server to proxy messages to the backend, as it encodes the backend response as either SWF byte code or JSON expressions which are sent back to the client.
Simple loading of XML data works in SOLO mode without use of the LPS server, in both SWF and DHTML, subject to the security policies of the runtime (Flash plugin for the SWF runtime , or browser XMLHTTPRequest security policy for DHTML) As a side note, I am very interested in JSON-RPC as a service ( http://json-rpc.org/) which could be supported in both the SWF and DHTML runtime without the use of any proxy server. Oliver Steele wrote a JSON expression parser for Laszlo, and JSON will of course parse directly using eval() in DHTML. Loading of JSON also is currently free of the security restrictions that XMLHTTPRequest has , which allows the client more power to access 3rd party services without needing to go through a proxy server on the host from which the app was loaded (which could be a good thing or bad thing, depending on how you feel...)
