Freelink autocomplete, a.k.a. 'Inline nodereference'

On a site with many nodes, it can be hard to remember the exact title of the one you're looking for when creating a Freelink. CCK Nodereference takes care of this by auto-completing node titles for you, but of course Drupal's autocomplete functionality only works for textfields, not textareas (e.g. body fields, where Freelinking operates).

I decided to combine the power of Freelinking and CCK Nodereference by writing this module, "Inline nodereference". Here's how it works: simply enable it, then go to edit a node, and start a Freelink like normal by typing [[. Start typing the name of any published node, and this module will fill in the rest for you. Keep typing to override the suggestion, or hit "enter" to accept it. Voila!

Obviously there's work to be done - there's no configuration settings, and I haven't tested it extensively at all. I'm also not sure whether it would be better off as its own module, or incorporated into Freelinking. Any thoughts are appreciated. Cheers!
