[support] page with multiple nodes configurable by unreg user

Hi all,

In my D7 site I have a list of nodes of a specific content type. I use the XPath Feeds module to create these nodes from an XML document. I know I can create a view to display those nodes, but I need to update the nodes using AJAX and I'd love to allow the visitor to move nodes to the top so the nodes he/she is most interested in stay visible easily. The rest has to be displayed using the sort order defined in the view.

What is the best way to use AJAX to update the nodes content in a view? How can I give the visitor (unregistered user) the ability to move nodes to the top?

Thanks for any help.
