I think a little more explanation of my scenario is needed:  I have a
client side javascript application -- a google maps mashup with a
number of overlays, that is manipulated entirely within the browser.
The browser model can be serialized in json format with a function
call eg:

myModel.toJson()  -- so what I want to end up with is a callback that
returns the json data to my Seaside component.

The basic questions is how to construct a the requests so to call some
function eg toJson() in the browser and return the string generated by
the function.

Thanks
