the problem is not the software. It is packaging and offering it attached to a personal domain name, in a way that it is truly portable and available **also** as a managed service.
My main proposal on how to do exactly this http://per-cloud.com/
My blog posts about it: http://stop.zona-m.net/tag/per...

Can't believe I only discovered this project today, when it's been running, it seems, for at least 6 months. Anyway, it seems very similar to what I just proposed, the percloud http:per-cloud.com With the difference, if I'm not mistaken, that the percloud would be an easier to use, preconfigured, locked down version of arkOS. Am I right?
