yes. Cédric was mentioning geonames to me. In the case of geonames you
can provide a "callback" parameter in the request (e.g.
&callback=myhandler), in that case the response from geonames looks
like this : "myhandler({"totalResultsCount":23,"geonames":[{"fcl":"P",
....]});". So if you use a ScriptProxy that response is evaluated by
the javascript engine, and myhandler gets executed.

Hope this clarifies it,
