Google has announced that they'll soon be offering RSS feeds for search results as a new feature of Google Alerts, which currently works only via e-mail. Google has not yet given a date for the new feature. I wonder if it'll work with Google Scholar as well.
I wish I'd known this at my RSS presentation a couple of weeks ago!
Update: Chris Lang points out in the comments that Google already offers this feature for blog searches!
