My Drupal module for editing nodes inline EditInline is at version ɑ-0.4. Just to summarize, the module lets you edit either the current node (or any other node where the title comes from Views or node template rendering) in a lightbox overlay. That means you don't always have to navigate to (or even know how to navigate to) a piece of content in order to edit it, making editing more accessible and intuitive.
Now you can also edit nodes in nodereference fields, while you're on the page to edit the current node! That means you can be on the edit page for e.g. a publication, but edit the author biography node attached to it by a CCK nodereference field. There's little edit buttons to the side of nodereference autocompletes which . Also, once you've edited the node in the lightbox overlay and it's closed, any title edits are also changed in situ to help you envisage how the page will look without having to refresh.
I did some of the work---mostly that leading from ɑ-0.2 to ɑ-0.3---during handy gaps between talks at Drupal Camp UK, held at BBC Manchester a couple of weeks ago. I wish I'd caught the wave of blogging about it at the time, as it was tremendous fun. The talks were all of a very high standard, but what felt more important to me was meeting people in the UK's Drupal community, and realising at first hand that the fun-loving, Drupal-interested, hard-drinking weirdos (that I'd always hoped were hiding here and there on the IRC channels and forums) really do exist.
