"Ubuntu One is not just a collection of services for
Ubuntu, it's a platform that you can build your own services on. In
this talk, Stuart Langridge explains some of the APIs that Ubuntu
One offers to developers, what they do, and how you can make use of
them. You'll see some examples of applications you might want to
build that take advantage of data storage in the cloud and
automatically-synchronised database backing for your apps, and
you'll get a glimpse of how to build programs to help people work
collaboratively through Ubuntu One both on the desktop and on the
web."
