Google Docs allows you to share a document with just the URL. The URL contains a key and authkey to identify the document and authorize access. This allows anonymous access to anyone who has the key.
I would like to access this type of shared document within an application. I've looked at the APIs, and haven't seen anything yet. It seems like this should be possible - since you can access such a document anonymously with a browser, why shouldn't an application be able to access the same document? Anyone know if/how this can be done?
