Actually I meant this in the context that we were trying to set up a
poll quickly under joomla (the CMS we use for QGIS.org). We didnt want
to spend (or have) hours to implement our own poll app - we just
wanted to take an off the shelf module and run with it.

In future we may adopt some of the ideas listed (I really like the
look of protovis that Barry mentioned) and incorporate them into the
django app suite we are building for QGIS.org.

Regards

Tim
