Regarding your second question, yes it is possible to use Google Drive as CDN. However, there is no documentation/tutorial to setup this. You can use these steps as a guide:
1. Setup your Google Drive. You can use this video as guide:

3. For CDN url, please use:
http://googledrive.com/host/[your Google Drive folder-id].
4. After done setup that, you need to put all these files in your Google Drive folder.
