Office Live is an amazingly flexible web design and business application tool, but understanding how to build customisation services around Office Live can be a bit of a hard one, especially when it includes things like Live ID from a client application.

The presentation video from Mix07 goes through the process by initially doing a couple of site design.  Then they build a reservation mini application that shares information between custom sharepoint lists internal to the site and present input/output information on the public site.  Then workflow is added to make the reservations move from requests to processes when the status is changed and update a calendar.  Remember that Office Live is built on a Windows SharePoint Services V3, so a platform that is already hotting up.

A simple mashup is built using the customer information and a Local.Live.com map.

Finally a client based application is created to log into the web service and then access the lists to update information.

While this is nothing revolutionary, it means that Office Live suddenly becomes another developer platform rather than just a web site and domain with e-mail addresses.
