1 hour later and I have made the Delicious Automatic Tagger
I've created a tool called DeliTag that automatically suggests tags for any page on kinlan.co.uk and submits them to your Delicious account. It's a quick process: hit "Goto", let the page load, click "Analyze" to see tag suggestions, choose the ones you like, enter your Delicious credentials, and press "Submit". Keep in mind, this currently only works on my site and requires IE6+ with Cross Domain Data Island support. Passwords are sent as plain text, mimicking Delicious's own method. Let me know if you'd like to see this developed further!
