The laws are build on different principles making them somewhat different. However, one of the things that we pay a lot of attention to is security resilience. The question is, "what has to be compromised before your data is compromised? and is there a way to detect it?" The storage is still something we are working on but you can believe it is a design goal.
The EU has very different approaches again to privacy law. I don't know you can compare them. They tend to be more lax with collection and stronger with use.
However, we can also help you install the software (open source, reviewed by developers all over the world) on your premises if you would prefer. So our best shot is only for those who really want to cloud host.
Could that make them capable of similar monitoring? Does the UK have stronger information privacy laws that the US doesn't?
