You could hack xmlrpclib to marshall those object, but I dont recommend i=
t.=20
Those objects can be big (but lazily evaluated), and you would be opening=
 a=20
significant denial of service vulnerability in your server.

I suggest you create a method (Python Script?) that makes the catalog que=
ry,=20
sanitizes the response by making sure it is not too big, and returns a=20
vanilla list or dictionary
