+XMLRPC allows software to make remote function calls over http.
 In the case of GRC, one can use XMLRPC to modify variables in a running flow graph.

+Place an "XMLRPC Server" block inside of any flow graph.
 The server will provide set functions for every variable in the flow graph.
 If a variable is called "freq", the server will provide a function set_freq(new_freq).
 Run the server example and experiment with the example client script.
