You can use an App Engine-hosted CGI proxy to validate Nick's hypothesis (e.g. http://proxypy.com/). http://www.delicious.com works; http://feeds.delicious.com does not.
The best way around this would be to use the Delicious API rather than scraping the feeds page: http://delicious.com/help/api. This appears not to block GAE (at a minimum, I can promise that Yahoo's BOSS API does not block GAE applications).
