Yes, so it does.

My ClusterManager class needs to throw Exceptions.  The ClusterManager
class doesn't really know anything about XMLRPC, as it's being wrapped
by a ClusterManagerServer class that starts the xmlrpc server and adds
a ClusterManager object to the xmlrpc server's handler.

Should the ClusterManager class throw XMLRPC excepts?  Or plain Ruby ones?
