Top Node provides a Views display type called 'node page' that displays a single node, using the same code that the node module does on that node's own default page.
RSS Remote Enclosure allows a user to attach a remote resource link (i.e. a media file on a different server) to any node (subject to user permissions).
This is a module that you can embed different blocks into one with tabs.
Those tabs switch with javascript based on jquery, shorten your sidebars without reducing the content of your page.
