[jQuery] Question about Interface elements

[jQuery] Question about Interface elements


Hello all,
I am in the early stages of developing a web portal and want to
provide a drag-n-drop of blocks, so users can pretty much configure
their own custom page. I am using Drupal as a CMS and found some
pretty well functioning modules which enable the DnD functionality.
I noticed that the Drupal modules in question (jquery_drag_drop,
jquery_interface and interface_sortable) use the "Interface" plugin
(http://interface.eyecon.ro). On inspecting this plugin it seems to me
that it offers some of the same functions as do ui.sortable.js,
ui.draggable.js and ui.droppable.js.
So the question is basically: is the Interface plugin superseded by
jQuery UI? So would I be using "old-tech" if I used the Interface
plugin?
It would be nice to get some input on this question.
Cheers,
Óskar
