would you consider adding a curse.com search feature?
I have a very simple one written in python using urllib2. If you would be willing to add it, I could add some UI for it in WUU and send you a diff. I started writing it after 3.0.2 when I had to search curse for the addons I used and then copy paste the ID out of the url. Or if you want I could just send you the scraper code.
