Looking through the comments, I think it would be great if someone can bundle all of this into a product which automatically applies security uodates and offers some form of visual dashboard to see the status of the system, errors, and logs of attempts to compromise the system. Furthermore a migration tool from GMail/Google-Apps/Drive would be super useful (+ one for Microsofts offerings).

I believe many would be willing to pay for such a service, and I would be open to collaborate on building such a product.

I can see here things like: - resale of hardware components and support agreements for paid subscriotions for the software - paid setup support - initial fee of the product - small subscription fee for updates
