What - no naughty users? ;-) Or companies that will try to persuade
users to install their "app" on the FreedomBox?

But most (non virtual) systems have no hardware RNG. I am using LXC as
virtualization technology. LXC shares the kernel between the VM's. Does
this mean i am getting "random" problems?

I am trained as an engineer. I design systems with the "worst case" in
mind.

Virtualization is widely used by the centralized services that dominate
the internet today. There are good reasons for this (not only security).
You may call my approach experimental (no problem with that), the
question is: is it the right approach? I belief it is, but i also belief
a system should be as simple as possible (but not simpler). I am looking
forward to the official FreedomBox architecture to compare with mine.
