Edit node fields from comment form

Hi,

I'd like to add some widgets to the comment form for privileged users that let them update some of the node's fields when they submit a comment. (Similar to how you can update Issue statuses when commenting on drupal.org issues.)

I'm hoping there's some combination of modules that can help me here. If my only option is custom development then that's cool, I'm just checking before I write a whole lot of code that's been written before.

Thanks!
