The link mention above (http://schweitzertech.com/wordpress/uncategorized/setting-up-mongodb-with-godaddy-hosting/) does not help in this particular case. This is not what the poster is looking for. This lets you run mongodb on the command line only. For production purposes, they would need to be able to edit the php.ini and add the mongodb php module, which you can not do on shared hosting. So, at this time, you can not use mongodb for a website on shared hosting.
