Is there an obvious way to do this in python?

Yes, but it's not (alas) supported by browsers...

It's not for "moving the scripts around", it's for remote objects - kind
of like Java's RMI, but, well, much more pythonic !-). Now the point is
that Python being very powerful when it comes to dynamism and
introspection, it should be possible to have a common client that
basically just knows how to connect to the application server (using
pyro). Once connected, the client asks the server for a set of objects
(forms, menus etc) and the corresponding data. These objects then use
the same mechanism to interact with the server. It's basically similar
to the interaction between a browser and a web app - in that the client
is potentially able to run any application sent by the server -, but
with much more  specialized client and app server and another protocol -
and no other language than Python.
