Development for Joomla 1.7 is ongoing.
There is an installer for joomla 1.7.
This contains both the component en module, the joomla-search plugin in not included and probably never will (use com_datafeeds search).
This installer combines joomla with the datafeeds component and example feeds and menu's like this site.
This is installer is highly recommended to get started.
Joomla 1.7 (live) site. A simple site but it shows all the elements of the component: the component itself, module with a 'menu', 'list' and 'custom' templates.
