ALL the features of Drupal (drupal.org ) hah.
Basicly, just trying to make WordPress also more like a Community blogging tool. Lots of interactive-ness, and such.
Take a look at http://www.wankercounty.net/ and http://www.robotskull.com/ , they have great interactive-ness.
(and i like the scrip with the user-signup w/ profile and auto cam link thing)
Other features I'd think would be cool is more than 1 picture/file upload with auto thumbnail.
