Google Sites - Embed Google Docs Video - Steegle.com
Google Sites now provides Google Docs Video embedding. This means you can now make use of some advantages over YouTube video embedding: add videos stored in Google Docs that do not provide links to related videos; and you can share the videos privately with more than 25 users, e.g. a whole Google Apps domain. The embed tool also lets you pick a custom size for the video without the need to use custom code.
