Hello Chuck,
It was useful to know the thought processes. I am however trying to understand how the "last piece of this jigsaw", which to me is the "last mile access to home or office" will be addressed. I just did some elementary maths on the bandwidth requirements: Assuming that a small office with just 20 people, use a cloud (with local thin clients) for their normal work. Also assuming that that most use windows and remote desktop into their Virtual desktops within the "cloud". For a seamless user experience, the link minimally has to be 1 Gige (100 MBps is a bit of a drag). That effectively means that each of the 20 users need a Gige connection on their machine/thin client. In effect, the office needs about 20Gige of external bandwidth into the cloud..and that just covers 20 users! Closer to the head, the bandwidth handling demands increase significantly more because of the accompanied aggregation.....this by itself seems to call for phenomenal investment in the last mile path, unless compression technologies improve vastly. Am I missing something here or are we looking at something really far into the future?

Hi -- you are assuming a thin client model only.

The CVP model says that the client has a full hypervisor and virtualized desktop machine running locally, and can operate autonomously if needed.

Changes get pushed/pulled as needed.

The bandwidth requirements in such a scenario drop dramatically.

    I try and write something new 1-2 times per week; less if I'm travelling, more if I'm in the office. Hopefully you'll find the frequency about right!
