Examples of Contextual Access to a Ubiquitous System

Looking for examples of a large enterprise-like system that has specific UX for contexual access.

Heres an example called "Ubranflow" which is like a Metro-wide Opertating System that is accessible via a browser from home, a user's mobile device, large touchscreen kiosks.  http://vimeo.com/26030147

Its a nice example of a single far-reaching system that has multiple interfaces, each one specifically desgined for the tasks of the context.

(And yes, the internet could fit this definiton.  As well as something that has desktop and mobile apps, like Facebook. Im looking for something thats a bit more explicity to designing different UIs for different contexts)

Thanks!
