[development] module with XML RPC

[Leo Burd]

Hello Andrew,

I've been using XML RPC a lot in my work.  I'm implementing a bunch of 
modules to provide telephone access to Drupal websites (voicemail, audio 
announcements, audio groups, etc.) and I use XML-RPC to handle all the 
communication between the telephone/voip server and the Drupal site.  You 
can have a look at a sample module that handles the upload/download/query of 
audio nodes here: http://drupal.org/node/43110

If you are interested, please get in touch with me outside the list and I'll 
send you the PHP .inc file that makes the XML-RPC calls to the above 
mentioned module.

Good luck,

Leo
