One of the topics at next09 is "Cloud Computing: The Network is the Computer (again)". For someone from Sun that sounds quite familiar and like a home-run. I guess I have to give it a try and submit a session:

Title: From Personal Computers to Personal Desktops as a Service

Abstract: Since the late 1970s “the desktop” is a powerful metaphor to interact with the computer. Despite the advent of new interaction paradigms – such as the web in the 1990s, and the social web and mobile devices in the present decade – the desktop remains at the center of a personal information workspace.
It is the desktop that matters, rather than the computer. Hence a virtual desktop infrastructure (VDI) provides the same desktop experience without the burden to manage the computer on your own. The PC itself becomes a metaphor as it is emulated in the data center and accessed with thin clients in the office and from mobile devices.
This talk gives an overview on the necessary VDI components: hypervisors, brokers, and client devices.
