Google Apps for Education's blogs
Google docs can be embedded in the vln using the iframe embed. There are restrictions on iframe embeds but docs (presentation, document, spreadsheet) are allowed.
In Edit mode, press on the HTML icon at the top right of the toolbar and insert the Google iframe embed code. Here, for the doc inserted here:
<iframe src="https://docs.google.com/present/embed?id=ajccz4ctdnqs_390dsmj4ddm&size=m" width="555" height="451" frameborder="0"></iframe>
