I'm using the Twitter JSONP public feeds in a javascript plugin that's loaded on 3rd party site (i.e. a bookmarklet/greasemonkey script) http://twitter.com/statuses/user_timeline/djnicolson.json?callback=mycallback
However, I'm finding that for certain Twitter users, this page is requiring authentication, which results in a nasty (disruptive) alert popup in the browser that asks users for their Twitter username/ password (try the above link to see what i mean) Is there a way around this? It would be nice if I could include another GET param that suppresses the authentication: i.e. http://twitter.com/statuses/user_timeline/djnicolson.json?callback=mycallback&suppressAuthentication=true would prevent the username/password popup from ever coming up and instead returns something in the form of: callback({'error':'tweetsProtected'}); (but without popping up the authentication thing)
