XMLRPC Method product available
The XMLRPC Method product provides support for remote procedure calls with the XML-RPC standard. This has been done before on Zope.org, but this product is in my opinion better documented and times out if the remote server is unresponsive.
We (the authors) intend to use this product for a number of things, such as looking up words in a dictionary, create maps of Europe and interfacing to our own search engine.
