New XMLRPC hooks are really easy to implement in WordPress.

Just add a sink to 'xmlrpc_methods'.  The incoming parameter is an array 
of supported methods.  Add a new array element using the method name as 
the key and the function name as the value:

add_filter('xmlrpc_methods', 'attach_new_xmlrpc');
function attach_new_xmlrpc($methods)
$methods['wordpress.getusers'] = 'wprpc_getusers';
return $methods;

Then implement the function you added to dispatch the RPC:

function wprpc_getusers($args)
$user_login  = $args[0];
$user_pass   = $args[1];
// Verify user
if (!user_pass_ok($user_login, $user_pass))
return new IXR_Error(403, 'Bad login/pass combination.');
// Good login, return the requested info...
return a_function_that_returns_user_data();

Consuming XMLRPC isn't hard either.  Feel lucky about the "Incutio 
XMLRPC" library used in WordPress for more info.
