Please note: this is not a direct answer to your question. I would personally go for a client-server model; not worrying what the server is written in or how it works. For some reason I have a scary thought of your widget pulling in 100million records and cross-tabbing two dimensions :) Don't worry about python bindings or such, why not try and find something that can take an OLAP query, maintain aggregates/computations on a DB that can possibly return in XML/JSON/ WHATEVER then just have your widget render visually the response and send out XML/JSON/WHATEVER on click events. Basically your widget is a renderer and UI to update the MDX/whatever instructions in the OLAP server. Of course, for small datasets, just nested dicts-of-dicts rendered would probably do. hth, Jon. -- http://mail.python.org/mailman/listinfo/python-list
