Embedding SkyDrive or Google Docs files in website

SkyDrive and Google docs allow you to embed Office docs in to your website or vle such as moodle. The main differences for me are that skydrive retains alot of the functionality of excel as you would expect for eg conditional formatting where as the google apps suite is better designed for collaboration in my opinion. Eitherway this is a great approach to getting learners working collaboratively on projects.
