I'm investigating the possibility of re-using Google Apps/Docs in a local hybrid desktop/browser application.
I've been going through the Google documentation on manipulating docs, eg. the Spreadsheet. I can't seem to find any info on actually hosting the UI. Is this possible, or does it require some form of permission from Google?
You want to basically embed an browser control in your application pointed at the URL of a Google Apps doc? You could use the Google Document List API to retrieve the documents for a user, then use the URLs of those documents in your embedded browser control.
You don't need Google's permission to do that; you're writing a browser with some extra smarts built in.
