Not sure I follow why the dict opts is only available with xmlrpc, must
be something specific to your code.

Optional arguments are possible, but if and only if they are omitted in
positional order working backwards from the end of the parameter list.

You are correct, optional arguments which do not preserve position are
not possible in xmlrpc, however wrappers can enforce the positional
requirements demanded by xmlrpc.

BTW, this is one of the downsides of xmlrpc. Xmlrpc was designed to be
butt-dumb simple, you don't get nuttin fancy for a vanilla bargain :-)
Simplicity has both virtues and limitations.
