The problem I have is with sending the focus away and then navigating back when
more than link needs to be described. On a complex UI with many links,
navigating back and forth from focusable targets (visible) is not something I
would want to experience as a user.

Extending the longdesc attribute (however far-fetched) might also include
setting properties of the new window to simulate lightboxes and other display
types.
